The decomposition of NH3 on platinum sur...

The decomposition of `NH_3` on platinum surface is zero order reaction. If rate constant is `4 xx 10^(-3) m//s`, how long will it take to reduce the initial concentration of `NH_3` from 0.1 M to 0.064 M.

Text Solution

Verified by Experts

Given that
`K = 4 xx 10^(-3) m//s`
[A] = 0.064 M and `[A_(0)] = 0.1 M`
For a zero-order reaction,
`K = 1//t[[A_(0)] - [A]]`
`4 xx 10^(-3) m//s = 1//t {(0.1 - 0.064)}`
t=9 second
