A 0.526 g sample of biphenyl, C12H10, was combusted in a bomb calorimeter. The calorimeter contained 500.g of water and the heat capacity of the bomb is 7.80 kJ. °C. The temperature of the entire calorimeter assembly changed from 24.61 °C to 26.22 °C Use the calorimetric data to determine the change in internal energy for the reaction in kJ.mol'. [5]
