The collision theory . . .
Discusses the collision theory of reaction rates, including the importance of activation energy and the Maxwell-Boltzmann distribution.
The effect of surface area on rate of reaction . . .
Describes and explains the effect of surface area on the rate of a reaction between a solid and a liquid or a gas.
The effect of concentration on rate of reaction . . .
Describes and explains the effect of changing the concentration on the rate of a reaction involving liquids or gases. If you are interested in rate equations, orders of reaction and rate constants, these are explained separately - see below.
The effect of pressure on rate of reaction . . .
Describes and explains the effect of changing the pressure on the rate of a reaction involving gases.
The effect of temperature on rate of reaction . . .
Describes and explains the effect of changing the temperature on the rate of a reaction, including the importance of activation energy and the Maxwell-Boltzmann distribution. The Arrhenius equation is dealt with separately - see below.
The effect of a catalyst on rate of reaction . . .
Describes and explains the effect of adding a catalyst to a reaction. This is an introductory look only. You will find a separate section dealing with catalysts in detail - link via the physical chemistry menu (see below).
