The rate contant for zero order reaction...

The rate contant for zero order reaction is `3xx10^(-2) mol^(-1)L.sec^(-1)`. After 25 sec. If the concentraition of reactant is 0.5 M them initial concentraition of the reactant is :-

A

1 M

B

1.25 M

C

0.5 M

D

0.75 M

Text Solution

Verified by Experts

The correct Answer is:
B
`A_(0)-A=Kt`
`A_(0)-0.5=3xx10^(-2)xx25`
`A_(0)0.5+0.75=1.25M`
