At the end of this activity, students should be able to explain how concentration affects reaction rates, discuss the effect of concentration in terms of the collision theory, explain the effect of pressure on the rate of reactions taking place in the gas phase, define the rate equation, rate constant and order of reaction, determine a rate equation from the relative rates at various concentrations of reactants, use rate equations for predicting relative and actual reaction rates and explain why the contact area affects the rate of heterogeneous reactions.
