Question: what is the enthalpy change for the decomposition of hydrogen peroxide?
Answer: The second interaction is characterized by a much lower value of activation energy and a higher heat release. The heat of the exothermic reaction is 8520 kJ∕kg H2O2 , whereas the heat released by self-decomposition of H 2 O 2 is 1410 kJ∕kg H2O2 (96 kJ/mol [7] ). ... ...
