The rate constant of zero order reaction...

The rate constant of zero order reaction is `2xx10^(-2)` mole L /sec. If the concentration of the reactant after 25 sec is 0.5 M, the initial concentration is

A

`2xx10^(-2)M`

B

1M

C

2M

D

`2xx10^(2)M`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(0)-C_(t)=Kxxt,C_(0)-0.5=2xx10^(-2)xx25,C_(0)=0.50+0.5,C_(0)=1M`
