![b)
Combustion reaction
In the same calorimeter, 1.04 g of benzoic acid were burnt completely (forming only
CO2 and H2O) under oxygen atmosphere, which caused a temperature increase of
8.8 K. Formulate the stoichiometrically correct reaction equation, calculate the molar
enthalpy of combustion AcHm and the molar enthalpy of formation AfHm of benzoic acid.
AHH20=-286.4 kJ mol-1
