Decomposition of H2O2 is a second order reaction. A solution of H2O2 labelled as 20 volumes was left open.Due to this, some H2O2 decomposed.To determine the new volume strength after 6 hours,10ml of this solution was diluted to 100 ml. 10ml of this diluted solution was titrated against 25ml of 0.025 M KMnO4 soln under acidic conditions.

calculate the rate constant for decomposition of H2O2.
