Solution

General Rate Law for Decomposition of Hydrogen Peroxide: The decomposition of hydrogen peroxide is often described by the rate law: $\text {Rate }=k\left[\mathrm{H}_2 \mathrm{O}_2\right]^n$
Where: - $k$ is the rate constant, - $n$ is the order of the reaction with respect to $\mathrm{H}_2 \mathrm{O}_2$.
Common Information: The decomposition of hydrogen peroxide is typically a second-order reaction with respect to $\mathrm{H}_2 \mathrm{O}_2$, meaning the rate is proportional to the square of the concentration of hydrogen peroxide.
