Factors That Affect the Rates of Reactions: Concentration, Temperature, Surface Area, Catalysts etc.

Shakur Chemistry Tutorials In this tutorial, we will explain how the factors of the nature of reactants, temperature, surface area, concentration of reactants, and catalysts affect the rates of chemical reactions. In this endeavor, we use an energy profile diagram to illustrate how the kinetic energy of reactant molecules is changed into potential energy. The concepts of energy of activation and the activated complex are reinforced. Molecular models are used to distinguish between successful and unsuccessful collisions. The Maxwell-Boltzman distribution curve for energy is used to illustrate how a change in temperature affects the number of particles that can react.
