Answer:
D. The concentration of the reactants.
Step-by-step explanation:
- The rate of the reaction is the change in the concentration of the reactants with time.
Rate ∝ [Reactants].
Rate of the reaction = k[Reactants]ⁿ.
where, k is the rate constant of the reaction.
n is the order of the reaction.
So, the rate of the reaction depends on the concentration of the reactants.
