The reaction x = Y is first -order overall and first-order with respect to the reactant x. The result of doubling the initial concentration of X will be to
a. shorten the half-life of the reaction
b. increase the rate constrant of the reaction
c. decrease the rate constant of the reaction
d. Shorten the time taken to reach equilibrium
e. double the initial rate
