Solution

The correct options are
A
increase the concentration of the reactants.

D
increase the temperature of the reaction

The rate of the reaction determines the speed by which the chemical reaction proceeds. It increases with an increase in the:

concentration of the reactants

pressure of the reacting gases

exposed surface area of the reactants

temperature of the reaction
