Answer

Explanation:

Step1: Write the decomposition reaction

The decomposition of hydrogen - peroxide is $2H_2O_2\rightarrow 2H_2O + O_2$.

Step2: Determine rate relationship

The rate of a reaction can be expressed in terms of reactants and products. For the reaction $2H_2O_2\rightarrow 2H_2O + O_2$, the rate of consumption of $H_2O_2$ is related to the rate of production of $O_2$ as $-\frac{1}{2}\frac{d[H_2O_2]}{dt}=\frac{d[O_2]}{dt}$. Rearranging gives $\frac{d[H_2O_2]}{dt} = 2\frac{d[O_2]}{dt}$, which means the rate of consumption of $H_2O_2$ is 2 times the rate of production of $O_2$.

Answer:

d) Rate of consumption of $H_2O_2 = 2\times$ Rate of production of $O_2$
