Summary
From the research, it is evident that cyclohexanone has a lower activation energy compared to benzaldehyde semicarbazone. This is apparent when the MW for cyclohexanone is recorded as 98.15g/mol and that one of the benzaldehyde as 106.121g/mol…

"Kinetic versus Thermodynamic Control in Competing Reactions"

From this research it is clear that the compound is normally found in structures that are crystalline. Their C-S bond is similar to the N-N bond which is normally retained in the semicarbazone. This compound has the lowest activation energy. ∆G=∆H- ∆S where ∆G is the Gibbs free energy, ∆H bonding energy, ∆S amount of disorder, and ∆G+ activation energy. Because ∆S is the minimum for most processes, the term could be assumed to ∆G-∆H. According to the thermodynamic versus the kinetic control of the compound, the energy reaction is remaining cold due to the small activation energy. When the reaction remains hot, there would be small energy for the compound to return to its initial state. On the other hand, the benzaldehyde semicarbonate’s activation energy is higher than that of Cyclohexanone semicarbazone because the packing of the crystal of the compound C9H11N3OS has stability due to two NH….o bonds of hydrogen. It has an amino acid which does not take part in the classical bond of hydrogen. The group of methyl is identified in two positions having almost similar occupancies. The compound that is most energetically stable is benzaldehyde semicarbazone. In the experiment, it is observed that benzaldehyde has a higher MW (106.121 compared to that of Cyclohexanone semicarbazone (98.15). It is also observed form the experiment that benzaldehyde semicarbazone has a slightly higher melting point than that of Cyclohexanone semicarbazone. ...
carbazone is cooled from a phase of isotropic, the nucleation genesis begins with the domain that is continuous forming planar structures having colour that is deep violet and displays reflections of the specular. The formed texture is the key traits of the cholesteric phase. This implies that the phase may look unstable and could change itself into a semetic phase. Further cooling causes the radical fringes to be displayed on the focal conic fans textures, and such a phase is linked to the phase of chiral smectic. The chiral smetic phase is extremely stable for different types of temperatures. Other homologues of the compound were identified as having different liquid phases that are crystalline. Such compounds display phases of cholesteric whenever they are exposed to high temperature. Response to question 3. Thermodynamic product C A B Kinetic product Diagram 4. Diagram 5. In this reaction whenever the pH is less than seven the reaction would be fast whereas when the pH is greater than seven the reaction would be slow. When the pH is much less than seven the reaction would be extremely slow thus not a nucleophilic reaction. Whenever the temperature is zero degrees Celsius, the reaction would be kinetic controlled, and the kinetic products would be made first. When the temperature of the reaction is about twenty five degrees Celsius, the reaction would form a mixture whereby there would be less energy for the reaction going back. At a temperature of about eighty degrees Celsius, the reaction would be a thermodynamic control reaction. Response to question 4. Kinetic control reaction or thermodynamic control reaction can dictate the reaction composition of a product mixture during the competing of the pathways directed towards different reactions and products.

At first, I thought 7 of pages is too much for such a question. But now I see it could not be done better. As the author starts you see the difficulty of the topic. I’ve read all at once. Great essay

Kinetic Theory of Matter
...these is a rule that heat transfers occur from the hotter body of matter to the colder matter and not the other way around, unless energy is expended against the natural process (from hot to cold). Relationship of heat to kinetic theory – the importance of this relationship is that kinetic energy in the form of heat can be utilized to operate machines and perform some kind of work. A close understanding of the kinetic theory of matter led to the formulation of the three laws of the theory of thermodynamics today, which are the following: the first law states that energy cannot be created or destroyed but merely converted from one form to another form (an example will be...

Thermodynamic Cycle Analysis
... of the engine without which the cycle is not possible. Therefore, the process of compression and expansion in the engine cannot be completely adiabatic. No heat engine can completely convert 100% of the heat to work. Thus, thermal efficiency of 100% is impossible to achieve. While an ideal cycle can theoretically show that the compression and expansion are adiabatic and the thermal efficiency is 100% (based on first and second law of thermodynamics), in practice, heat loss is inevitable and thus practically, thermal efficiency of 100% is impossible.

Moslems worship Allah, the God, who is the only god over the people. They deny the trinity offered by Christianity as the distortion of the divine truth. It is believed that Muhammad was the last prophet, whose task was to tell the truth about God to people. The words of Muhammad were put down in a book called Quran, which is written in ancient Arabic, while the translations are treated as interpretations of Quran. This holy book teaches that only true believers will be rescued on the day of the Last Judgment, while the rest...

Teaching versus Control a Parenting Challenge
...Teaching versus Control: Parenting Challenge Parenting is really a challenging and complex role. It is a heavy responsibility that lies sometimes onjust a single parent. Each parent is different and the various parenting styles have a definite effect on the child behavior. There are binaries that confuse the parents as it is difficult for them to determine the demarcation line between those pairs. For example: punishment versus discipline and teaching versus control. This paper concerns with the latter. Though there are huge volumes of self-help books available on parenting, psychology, medicine, sociology and education are some of the areas that have shown immense interest in parenting styles and child behavior and have come... from...

...Factors affecting the rate of a chemical reaction – The kinetics of a Thiosulfate Solution Introduction: Various approaches are used to study the kinetics of reactions. A usual procedure is to monitor some property, such as intensity of color due to a reactant or product, which changes during the course of a reaction. In the present experiment, the priority studied is the precipitation of a product, sulfur, which forms when solution of hydrochloric acid and Thiosulfate are mixed. When a solution of Thiosulfate is acidified, the following reaction takes place: S2O32- (aq) + 2H+ (aq)  H2O + SO2 (g) + S (s) On mixing a solution of acid,...
