Zero order reaction

Question

The zero order reaction A → Products takes 63.5 minutes for the concentration of A to decrease from 0.970 M to 0.241 M. What is the value of k for this reaction?

Answer 1

The integrated rate equation for a zero order reaction is ...

[A] = [A]_o - kt

Solving for k, we have...

0.241 M = 0.970 M - (k)(63.5 min)

-0.729 M = -63.5 min * k

k = 0.0115 M/min
