The decomposition of NH3 on a platinum surface is a zero order reaction. What time will be taken to reduce the concentration of Nh3 from 0.1 M to 0.064 M? K= 4*10^-3

Answer 1

The integrated rate law for zero order rx is

[A] = -kt + [A]_o

0.064 M = -4x10^-3 M/s t + 0.1 M

-0.036 M/-4x10^-3 M/s

t = 9 seconds
