The decomposition of `H_2 O_2`, in the presence of Iodide ion has been found to be first order in `H_2 O_2` .
The rate constant has been found to be `1.01xx10^-2 min^-1`. What concentration of `H_2 O_2` would give rate of `1.12 xx 10^-2 mol L^-1 min^-1?

Text Solution

Verified by Experts

`2H_2O_2 overset(I^(-))(rarr) 2H_2O_2 + O_2`
Rate Exprution = `k [H_2O_2]`
`1.12 xx 10^(-2) = 0.01 xx 10^(-2) xx (H_2O_2)`
`[H_2O_2] = 1.11 "mol" l^(-1)`
