How long will it take for the concentration of A to decrease from 1.400 M to 0.383 for the zero order reaction A → Products? (k = 0.0345 M/s)

Answer 1

Integrated rate law for zero order reaction is...

[A] = [A]o - kt

[A]o = 1.400 M

[A] = 0.383 M

k = 0.0345 M/s

t = ?

0.383 = 1.400 - 0.0345t

0.0345t = 1.017

t = 29.5 sec
