32. Given the following thermochemical equation, calculate ÎE (in kJ) at 30.00. 2 N2 (g) O2 (g) â 2N20 (g) + AH- +163.2 kJ 33, when one mol of C8H18 () was combusted at 25.0°C in a bomb calorimeter, 5450 kJ of energy were released. Given this information, calculate the heat of reaction (i.e., enthalpy change) in kJ for the following reaction. C8H18 () 12.5 O2 (g) 8 CO2 (g) + + 9 H2O (r) â
