The rate constant of a zero order reacti...

The rate constant of a zero order reaction in A is `0.003 "mol L"^(-1) "sec"^(-1)`. How long will it take for the initial concentration of A to fall from 0.10M to 0.075 M ?

Text Solution

Verified by Experts

`t=([A]_0 -[A])/k=(0.10-0.075)/0.003`=8.3 sec
