If the initial concentration of A is 0.407 M, and the rate constant for this reaction is 0.0341 M s^-1 at 400, What is the half-life of this reaction?

Answer 1

The units of the rate constant, Ms^-1, tells us this is a zero order reaction.

The half life for a zero order reaction is t_1/2 = [A]o / 2k where Ao is the initial concentration.

t_1/2 = 0.407 M / (2)(0.0341 Ms^-1)

t_1/2 = 5.97 s
