The rate constant of the reaction --- ...

The rate constant of the reaction ---
`2H_2O_2(aq) to 2H_2O(l) + O_2(g)` is `3xx10^-3 "min"^-1`, At what concentration of `H_2O_2`, the rate of reaction will be `2xx10^-4 Ms^-1`?

Text Solution

Verified by Experts

Rate =`k[H_2O_2]`
or, `2xx10^-4=(3xx10^-3)/(60)xx[H_2O_2]`
`therefore [H_2O_2]=4 M`
