The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. For example, the oxidation of iron under the atm...

Catalyst Reaction Rate; J0520; Objectives/Goals; My project is to study the effect of two variables, temperature and substrate concentration on the decomposition of hydrogen peroxide into oxygen gas and water with two catalyst organic catalase and inorganic manganese dioxide (MnO2) and measure the rate of the reaction.

Catalysts speed up chemical reactions. Only very minute quantities of the catalyst are required to produce a dramatic change in the rate of the reaction. This is really because the reaction proceeds by a different pathway when the catalyst is present.

Background Knowledge: Enzyme: Enzymes are proteins which act as a Biological Catalyst. A catalyst alters the rate of reaction without itself changes. Research indicates that enzymes combine with the molecules they act upon (called Substrates) to form an enzyme-substrate complex.

DISCUSSION A catalyst is a substance that is added to a reaction to increase the reaction rate. The catalyst allows the reaction to proceed by an alternate reaction mechanism with a lower activation energy. A catalyst is not consumed in a chemical reaction.
