Q. $H_2{O}_2\to H_{2}O+O_2$
The rate constant of this reaction is $2\times {10}^{-2}mi{n}^{-1}$ (at certain temperature) and reaction is started with $0.5M$ concentration of $H_2{O}_2$, after $23.03min$ the reaction was suddenly stopped by lowering the temperature and remaining $H_2{O}_2$ was completely reacted with $NaOCl$, if number of moles of $O_2$ produced in second reaction is $\frac{1}{x}$. Find $x$.
