Consider the reaction with an initial concentration of Ao= 6.00Mand a half-life of 65.0 minutes.

 If this reaction is zero order with respect to A, how many minutes will it take for the concentration of A to reach 0.504M?

    The half-life of a zero-order reaction is related to the initial concentration and the rate constant, k, as:

    t1/2 = [A]o/2k

    So,

    k = [A]/2(t1/2)

    k = 6.00/2(65min) = 0.04615 M/min

    Then, the integrated rate law for a zero-order reaction is:

    [A] = -kt + [A]o

    0.504 M = -0.04615 t + 6.00

    t = 119 min
