Decomposition ofH_(2)O_(2) is a first order reaction. A solution of H_(2)O_(2) lebelled as "16.8 V" was left open. Due to this, some H_(2)O_(2) decomposed. To determine the new volume strength after 2.303 hours, 20 mL of this solution was diluted to 100 mL. 25 mL of this diluted solution was titrated against 37.5 mL of 0.02 M KMnO_(4) solution under acidic conditions [Given : STP is 1 atm and 273 K] Calculate the rate constant (in "hr"^(–1)) for decomposition of H_(2)O_(2).
