In a second-order reaction, what is the relationship between the rate and the concentration of the reactants?

A. Rate is proportional to the square of the concentration
B. Rate is inversely proportional to the concentration
C. Rate is independent of concentration
D. Rate is proportional to the product of the concentrations

Answer: Rate is proportional to the product of the concentrations


Additional Information: In second-order reactions, the rate is dependent on the concentrations of reactants, either one squared or two multiplied.
