When 0.600g of biphenyl undergoes combustion in a bomb calorimeter, the temperature rises from 25.4 degrees Celsius to 30.1 degrees Celsius. Find Delta E(rxn) for the combustion of biphenyl in kJ/mol biphenyl. The heat capacity of the bomb calorimeter, determined in a separate experiment, is 5.86 kJ/degrees Celsius.
