Answer:
The rate decreases as the concentration of the reactants decreases.
Explanation:
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time. This is because a reactant is consumed in a reaction while products builds in that same reaction.
The reaction rate therefore is directly proportional to the concentration of the reactants.
