Question

For combustion of hydrogenH2(g) + 1/2 O2(g) -> H2O(l) thereaction enthalpy is -286 kJ/mol and the reaction Gibbs free energyis -237 kJ/mol. Calculate the amount of heat that will be given offby burning 1 mole of hydrogen gas (find result in kJ Please show final answer For combustion of hydrogenH2(g) + 1/2 O2(g) -> H2O(l) thereaction enthalpy is -286 kJ/mol and the reaction Gibbs free energyis -237 kJ/mol.

Explanation / Answer

enthalpy H = -286 kJ/mol
Gibbs free energy G = -237 kJ/mol. the amount of heat that will be given off by burning 1 mole ofhydrogen gas = H -G                                                                                                                  = -49 kJ /mol
