The rate constant of the reaction 2H2O2(...

The rate constant of the reaction `2H_2O_2(aq)rarr2H_2O(l)+O_2(g) " is " 3 xx10^(-3)"min"^(-1)`
At what concentration of `H_2O_2` , the rate of the reaction will be `2xx10^(-4) Ms^(-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]`
