Chemical Reactions Catalysts
Introduction In chemical reactions catalysts are used in order to speed up the reaction. Their ability is to decrease the activation energy of the reaction while they are not used within the reaction. Catalysts usually consist of one or more active components imposed on surface of an oxidation material referred as catalyst support. Support material acting as building block for catalysts has many advantages such as: - Maximizing the surface area of the active components

Hydrogen Peroxide Chemical Reaction Rate
Discussion: In this experiment, the rate of reaction will be investigated. When hydrogen peroxide is added to a solution of potassium iodide, the iodide ions are slowly oxidized according to the equation: H2O2 (aq) + 3I- (aq) + 2H+ (aq) I3- (aq) + 2H2O (l) This reaction can be modified by the introduction of a small amount of S2O32- (aq) and starch indicator. The reactions are shown below: H2O2 (aq) + 3I- (aq) + 2H+
