Answer:

A. How the concentration of the reactants affects the rate of a reaction

where,

rate: rate of the reaction

[A] and [B]: molar concentrations of the reactants

k: rate constant

a and b: reaction orders

As we can see, the rate law shows how the concentration of the reactants affects the rate of a reaction.
