Solution: A decomposition reaction, with a rate that is observed to slow down as the reaction proceeds, is found to have a half-life that depends on the initial concentration of the reactant. Which statement is most likely true for this reaction?
(a) A plot of the natural log of the concentration of the reactant as a function of time is linear.
(b) The half-life of the reaction increases as the initial concentration increases.
(c) A doubling of the initial concentration of the reactant results in a quadrupling of the rate.

(b) The half-life of the reaction increases as the initial concentration increases.
(c) A doubling of the initial concentration of the reactant results in a quadrupling of the rate.
