Which of the following statements is true for a first-order reaction?

A. The rate is independent of the concentration of reactants
B. The half-life is independent of the initial concentration
C. The rate is directly proportional to the concentration of one reactant
D. The rate depends on the square of the reactant concentration

Answer: The half-life is independent of the initial concentration


Additional Information: For a first-order reaction, the half-life is constant and does not depend on the concentration of reactants.
