The combustion of toluene has a Erxn of -3.91 * 103 kJ/mol. When 1.84 g of toluene (C7H8) undergoes combustion in a bomb calorimeter, the temperature rises from 23.22 C to 35.67 C. Find the heat capacity of the bomb calorimeter. 15. Find Hrxn for the reaction: N2O(g) + NO2(g) 3 NO(g) using the following reactions. 2 NO(g) + O2(g) 2 NO2(g) H1 = -113.1 kJ/mol N2(g) + O2(g) 2 NO(g) H2 = +182.6 kJ/mol 2 N2(g) + O2(g) 2 N2O(g) H3 = +163.2 kJ/mol
