As the frequency of successful collisions decreases.

Explanation:

Collision Theory states that for reaction collision between reactant species must occur with sufficient energy (activation energy) and correct orientation (can be relevant). As the reactants react fewer remain and so the frequency of successful collisions decreases. Hence the rate of reaction decreases.
