9.2 Catalysis What is a catalyst? A catalyst is a substance that increases the rate of reaction but is chemically unchanged at the end of the reaction Catalysis is the increase in the rate of chemical reaction by a catalyst Characteristics of catalysts: Catalysts...
9.1 Factors Affecting the Rate of Reaction How to increase the rate of reaction? According to the collision theory, the rate of reaction will increase if: the frequency of collision and effective collision increases the proportion of particles with energy greater...
9.1 Rate of Reaction What is the rate of reaction? Rate of reaction is the change in concentration of reactants or products per unit time. It refers to the rate of product formed or the rate of reactant used up A balanced chemical equation gives no information...
CHAPTER 9: Rate of Reaction Rate of Reaction Factors Affecting Rate of Reaction Catalysis Learning outcomes: explain and use the terms: rate of reaction, activation energy and catalysis explain qualitatively, in terms of collisions, the effect of concentration...
