"Kinetic of the catalytic decomposition of hydrogen peroxide"

Download file to see previous pages Calculate the activation enthalpy of the decomposition of hydrogen peroxide solution when (manganese (IV) oxide & Iron (III) chloride) act as a catalyst and compare their effectiveness. A standard procedure for working out the enthalpy should be applicable for both case studies.
Find the order of each reactant and use the order to explain the mechanism of the same. It should involve comparison of the rate of reaction of hydrogen peroxide with manganese (IV) oxide and Iron (III) chloride. Such a comparison would be easy under standard conditions. Graphical representations of the course of reactions with varying quantities of reactants will facilitate comparison.
Chemical kinetics studies chemical reactions under different conditions. Chemical kinetics explains the nature and order of reactions. Knowledge of kinetics is important in conducting experiments to identify unknown substances. It is also vital in determining reactivity of chemical substances under non-specific conditions. Catalysts find use in facilitating reactions, including manganese (IV) oxide, potassium iodide, and an enzyme catalyst. However, in my investigation, I will only choose two catalysts to use and I will focus on the effect of changing concentration, quantity, temperature and type of catalysts in order to investigate the rate of reaction changed under various experimental conditions.
Hydrogen Peroxide (H2O2) in an aqueous decomposes very slowly under ordinary conditions which means the reaction will happen without the catalysts being used. The reaction is dependent on the internal energy that disordered and random motion of molecules contributes. Increase temperature will increase molecular speed, on the other hand lower the temperature, lower the internal energy of a substance. However, temperature is indirectly proportional to internal energy. Temperature is a measure of the kinetic and not a reflection of the whole internal energy. ...Download file to see next pagesRead More

Kinetic Theory of Matter
...KINETIC THEORY OF MATTER This is a study that seeks to explore the concept of kinetic theory of matter, the concepts of heat and temperature and how they relate to each other. In this paper, I have also explored the relationship between heat and temperature and how they differ from one another. The Kinetic theory of matter is a theory that describes states of matter. There are three states of matter namely solids, liquids and gases. This theory states that matter is composed of particles that are in constant motion. These particles are either atoms or molecules. The particles in solids cannot move to another location but they can only vibrate because they are closely held to each other....

Kinetic Theory of Matter
...? Kinetic Theory of Matter (Heat and Temperature) of KINETIC THEORY OF MATTER Kinetic theory – this particular theory says that all three states of matter (gases, liquids and solids) possess some energy resulting from the constant motions of the atoms and molecules that comprise matter. This energy from motion is called as kinetic energy. This particular energy can be measured through the temperature of that matter (whether it is in gas, liquid or solid form) or stated differently, the hotness or coldness of matter can known by measuring its temperature. This means that more kinetic energy in matter makes it hotter, or conversely, less kinetic energy makes the matter colder. There are some characteristics of kinetic energy; among... these is...

Interpret Research on Decomposition Analysis
...? Decomposition Analysis Task: Decomposition Analysis Return of assets (ROA) is a business technique used to know or calculate how the assets of a certain company are effective in generating income. In calculating the return on assets, one divides the net income by the value of total assets. It simply tells how much one can get from a certain value of assets. This way, the company gets an idea on what it can do with its assets. Common stakeholders in a company use return on equity to measure the rate of interest of ownership. This shows how a company uses funds from investors to generate a growth in the earnings. The relationship between return on assets and return on equity is that return of assets shows...

Action Of Enzyme Catalase On Hydrogen Peroxide
... known, with rates approaching 200,000 catalytic events/second/subunit (near the diffusion-controlled limit). (http://biology.kenyon.edu/BMB/Chime/catalase/frames/cattx.htm) Hydrogen peroxide is formed as a waste product of metabolism in many living organisms. It is toxic and must be quickly converted into other, less dangerous, chemicals. To manage this problem, the enzyme catalase is frequently used to rapidly catalyse the decomposition of hydrogen peroxide into harmless oxygen and water.(Wikipedia-the free online dictionary) There are certain factors that influence the activity of catalase: Substrate Concentration Temperature pH Salt Concentration Presence of Inhibitors Presence of Activators Hence even if the same experiment...

...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, such as HCI, and a thiosulfate solution, there is an initial...

Measuring The Heat of Decomposition of Hydrogen Peroxide
...Decomposition of hydrogen peroxide 28/10 Introduction H2O2 decomposes through a redox reaction to form water and oxygen: 2H2O (aq) ------------------> 2H2O(l) + O2(g) This reaction is very slow since H­2O2 is a very stable compound. It can remain stable for several years. To speed up the reaction a catalyst is used. Examples of catalysts that can be used are potassium iodide, catalase (Williams) and iron (III) nitrate. The redox reaction of H­2O2 is an exothermic kind. By measuring how the temperature changes when H­2O2 and a catalyst are mixed, it is possible to determine the enthalpy of decomposition H­2O2. This experiment will determine the enthalpy of decomposition of H­2O2 ­when it is mixed with potassium iodide... ...
