"Compare and contrast thermodynamics and kinetics"

Download file to see previous pages It studies the factors that affect reaction rates and the mechanisms in which the chemical reactions proceed. Kinetics is concerned with the measure of reaction rates of that proceed under specific conditions of pressure, temperature and concentration. This paper seeks to compare and contrast kinetics and thermodynamics.
Thermodynamics is complementary to the theory of kinetic. It provides the relations between the physical properties of a system under specified measurements, while kinetics enables the calculations of the magnitude of the system’s properties. Thermodynamics determines the equilibrium of the reaction, the constant of the equilibrium, and it is also determined by enthalpy and entropy. On the other hand, kinetics determines the rate and speed of the reaction, the constant of the rate and it is determined by the activation energy. Thermodynamics and kinetics are hence related to one another in a chemical reaction.
As described in the above paragraph, a chemical reaction contains aspects of both thermodynamics and kinetics. The kinetics related quantities are constant rate which is associated with the required activation energy for reaction to move forward, while thermodynamics is associated with the energy difference that results from a free energy released in the process of a chemical reaction. Although kinetics defines the speed and rate of reaction, they don’t specify conditions of the equilibrium. On the same note, thermodynamics only details the equilibrium conditions and says nothing about the rate and speed of reaction; hence the two are related and complement each ...Download file to see next pagesRead More

...?This is a comparison and contrast between Cinderella and Ashputtle. Both the stories are very similar with only minor differences which will be discussed below. Both the stories essentially follow the same storyline but there are some changes. Charles Perrault’s focuses on the simplicity and kind heartedness of Cinderella who never wishes badly for anyone. Her father is described as a weak individual and is not a prominent character in the story (Perrault). More focus is kept on Cinderella and her fairy Godmother. The Fairy Godmother keeps on telling Cinderella to be a good girl and Cinderella listens to her. Cinderella is shown as a very kind-hearted and innocent girl who always does good to others. Hence in the end Cinderella... her...

...Comparison and Contrast between two close friends Introduction My two closest friends are John and George. We have been friends since third grade and have to this day, served as one another’s support system for as long as we have known each other. George is very athletic while John is the geek in the group. The latter has interests in computers and knowledge in general, while the former plays football and recently made it to be the school’s first team as a quarter back. We are currently in the same school though different classes but share every opportunity in between the lessons and available free time to chat and share jokes. Personality From the above brief description, my two friends have very distinct personalities....

...Insulated Pizza Delivery Bags Thermodynamics, the study of energy and its transformations, has a set of four laws that govern the behavior of energy.Scientists have theorized that energy can be exchanged between physical systems as heat or work. They also put forward the existence of a quantity named entropy which can be defined as an isolated system that is in thermodynamic equilibrium. On the microscopic and subatomic level an isolated system as insulated pizza bags contains particles whose motion defines its properties, The first law of thermodynamics: 'The internal energy of an isolated system is constant.' Therefore the internal energy of the content of the pizza bag remains...

... Compare and contrast Spring and Fall There is a certain charm and quality to a Spring day that is missing from the season of Fall. There is the feeling of lightness and life during the months of spring, it is apparent in the scent of lilacs and can be seen in the myriad of flowers coming into bloom and plants putting on their verdant dresses of green. The warmth in the air is tempered occasionally by a cooling breeze and the sounds of birds singing their songs of creation abound. Even the word “Spring” has a sense of liveliness, energy and effervescence. Phrases like “Spring Ahead” come to mind as positive reinforcements of this season. The word “Fall” on the other hand (need I say more), connotes perhaps a “Fall from Grace... Compare and ...

...flywheel being brought to a stop by a brake. The First Law of Thermodynamics primarily states that there is no way that energy can emerge out of creation nor be given to destruction for it can only be transferred between systems or be changed from one form to another. For instance, a rotating flywheel in motion possesses a ‘rotational energy’ which may also be treated a kinetic energy. Once a brake is applied to stop it, then the flywheel comes to rest the moment its kinetic energy is converted to potential energy which the device stores from the previous state of motion. Q1.3b If a fluid is at rest in a tank, does it have internal energy? First of all, an internal energy of a...

In this paper, we shall look at two articles with different approaches to education and we shall compare these approaches to each other. In this paper, we shall compare the different approaches that these two authors have suggested as a remedy for filling up the gaps in education both in the workplace and at school. We shall look at the following: an approach to education, failures in the education system, and...

...habit. For example, a person may decide that starting today; they will never smoke, and then stick to their decision. Secondly, a person may break a bad habit by tapering off, which highly bases on harm reduction. Bad habits result in harm, so one may choose to reduce the harm by reducing the number of times they engage in the bad habit. A person will start cutting back on the bad habit, like gradually rolling back the bad habit until it finally disappears completely. For example, a smoker used to five cigarettes daily may decide to smoke only two, then one, and finally quit smoking. The two ways present different conditions, so one may choose depending on how well they can cope. Comparing the two, abstinence may be...

Furthermore, the representation of class is one in which the viewer comes to the realization that the moneyed aristocracy/bureaucracy is the only mechanism through which the average societal stakeholder can hope to get ahead. As a direct result of this realization and portrayal, the protagonists of the film find it necessary to ingratiate themselves with these individuals as a means of pursuing this dream. Interestingly, the second film that will be discussed within this comparison and contrast, “All about My Mother”, represents a differential between those individuals that live within the provinces and those that live within...

...from the readers. In Chang’s writings, the author does not use sound devices. Thirdly, the use of sensory details and figurative language is another aspect of writing style that can be used to compare and contrast two or more authors. In general, both writers employ literally devices that appeal to the senses of the reader. Both writers extensively use similes in their writings. In Chang’s Lust Caution, examples of similes used include: “…through the glass doors like a sea dragon” (Chang, 28), “what sounded like Hindi upstairs” (Chang, 28) and “a nose squalled like a lion’s muzzle” (Chang, 30) among others. In Hsun’s Medicine, some of the similes used include “the man’s eyes shone…. like a famished...

However, Friedman’s generation tries to look into the techniques of handling the challenges of global warming and other social, economic, and...
