0Decomposition of \( \mathrm{H}_{2} \mathrm{O}_{2} \) is a first order reaction. A solution of \( \mathrm{H}_{2} \mathrm{O}_{2} \) labelled as 20 volume was left open. Due to this some \( \mathrm{H}_{2} \mathrm{O}_{2} \) decomposed. To determine the new volume strength after \( 6 \mathrm{hr}, 10 \mathrm{~mL} \) of this solution was diluted to 100 \( \mathrm{mL} .10 \mathrm{~mL} \) of this diluted solution was titrated against \( 25 \mathrm{~mL} \) of \( 0.25 \mathrm{M} \mathrm{KMnO} 4 \) acidified solution. Calculate the rate constant for the decomposition of \( \mathrm{H}_{2} \mathrm{O}_{2} \).
