15.3 - Spontaneity of a reaction

15.3.1: Calculate the standard entropy change for a reaction (? SØ ) using values of absolute entropy

15.3.2: Calculate Gibb's free energy change (? GØ ) for a reaction using the equation ? GØ = ? HØ - T ? SØ or by using values of the standard free energy change of formation, ? GfØ
