0.5 g of benzoic acid was subjected to combustion in a bomb calorimeter at `15^(@)C` when the temperature of the calorimeter system (including water) was found to rise by `0.55^(@)C`. Calculate the heat of combustion of benzoic acid (i) at constant volume and (ii) at constant pressure. the thermal capacity of the calorimeter including water was found to be 23.85 kJ.
