The rate constant of a zero order reacti...

The rate constant of a zero order reaction is` 0.2 mol L^(-3) h^(-1)`. If the concentration of the reactant after 30 min is 0.05 mol ` dm^(-3)`, then its initial concentration would be

A

`0.01 "Mol " dm^(-3)`

B

`0.15 "Mol " dm^(-3)`

C

`0.25 "Mol"dm^(-3)`

D

`4.00 "Mol"dm^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
B
In 30 minutes 0.1 mol `dm^(-3)` react .Remaining concentration is 0.05 mol `dm^(-3)`
therefore , initial is `0.10 +0.05 = 0.15 mol dm^(-3)`
