Decomposition of $\displaystyle \mathrm{H}_2 \mathrm{O}_2$ follows a first order reaction. In fifty minutes the concentration of $\displaystyle \mathrm{H}_2 \mathrm{O}_2$ decreases from $\displaystyle 0.5$ to $\displaystyle 0.125$ M in one such decomposition. When the concentration of $\displaystyle \mathrm{H}_2 \mathrm{O}_2$ reaches $\displaystyle 0.05$ M , the rate of formation of $\displaystyle \mathrm{O}_2$ will be :
Official answer
(2)
$\displaystyle 6.93 \times 10^{-4} \mathrm{~mol} \mathrm{~min}^{-1}$
