Problem
Decomposition of H2O2 is a first order reaction. A solution of H2O2 labelled as 20 volume was left open. Due to this some H2O2 decomposed. To determine the new volume strength after 6 hr, 10 mL of this solution was diluted to 100 mL. 10 mL of this diluted solution was titrated against 25 mL of 0.25 M KMnO4 acidified solution. Calculate the rate constant for the decomposition of H2O2 .
