When o.514 g of biphenyl (C12H10) undergoes combustion in a bomb calorimeter, the temperature rises from 25.8 to 29.4 degree Celcius. Find delta energy reaction for the combustion of biphenyl in KJ/mol biphenyl. The heat capacity of the bomb calorimeter, determined in a separate experiment, is 5.11 KJ/Degree Celcius.
