Document Summary

The heat of combustion of benzoic acid is -26. 42 kj/g. P = 84 atm w= -pv w = - (84 atm)(101325 pa/atm)(27. 5l) w = - 2. 34 x 105 j. Question 3 (5 marks) from the following thermochemical equations, calculate rh for the reaction: 2 so2(g) + o2(g) 2 so3(g) rh = -197. 8 kj/mol. 2 no(g) + o2(g) 2 no2(g) rh = -114. 14 kj/mol. 2 so2(g) + 2 no2(g) 2 so3(g) + 2 no(g) rh = -83. 66 kj/mol. 12 (2 so2(g) + 2 no2(g) 2 so3(g) + 2 no(g)) rh = 12(-83. 66 kj/mol) So2(g) + no2(g) so3(g) + no(g) rh = - 41. 83 kj/mol.
