If decomposition of H(2)O(2) is a first ...

If decomposition of `H_(2)O_(2)` is a first order reaction , how long would it take to complete one- third of the decomposition ? The rate constant of this decomposition reaction is `3xx10^(-2)"min"^(-1)`.

Text Solution

Verified by Experts

`t=(2.303)/(k)log.(a)/(a-x)=(2.303)/(3xx10^(-2))log.(a)/(a-(a)/(3))=13.52min`
