The rate constant of the reaction 2H(2...

The rate constant of the reaction
`2H_(2)O_(2)(aq) rarr 2H_(2)O(l) + O_(2)(g)` is `3 xx 10^(-3) min^(-1)`
At what concentration of `H_(2)O_(2)`, the rate of the reaction will be `2 xx 10^(-4) Ms^(-1)` ?

A

`6.67xx10^(-3)M`

B

2 M

C

4 M

D

`0.08M`

Text Solution

Verified by Experts

The correct Answer is:
C
Rate = `k[H_(2)O_(2)]^(1)`
`2xx10^(-4)=(3xx10^(-3))/(60)xx[H_(2)O_(2)]`
`[H_(2)O_(2)]=4M`
