When 0.596 g of biphenyl (C12H10) undergoes combustion in a bomb calorimeter, the temperature rises from 26.4°C to 30.4°C.
Find ΔErxn 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/°C.
C12H10(s) + 14.5 O2(g) → 12 CO2(g) + 5 H2O(l)
ΔErxn = ___ kJ
