The rate constant for a zero order react...

The rate constant for a zero order reaction is `2xx10^(2)` mol `L^(-1) "sec"^(-1)` .If the concentration of the reactant after 25 sec is 0.5 M., the initial concentration must have been

0.5 M

1.25 M

12.5 M

1.0 M

Text Solution

Verified by Experts

The correct Answer is:

`C_(0)-C_(t)=K.t,(C_(0)-0.5)=2xx10^(-2)xx25,C_(0)=0.5xx0.5=1M`
