The rate constant of the reaction : `2H_(2)O(aq)to2H_(2)O(l)+O_(2)(g)` is `3xx10^(-3)min^(-1)`. At what concentration of `H_(2)O_(2)`, the rate of the reaction will be `2xx10^(-4)M s^(-1)` ?

A

`6.67xx10^(-3)M`

B

`2M`

C

`4M`

D

`0.08M`

Text Solution

Verified by Experts

The correct Answer is:
C
Rate `=k[H_(2)O_(2)]`
`2xx10^(-4)=(3xx10^(-3))/(60)xx[H_(2)O_(2)]`
`[H_(2)O_(2)]=4M]`
