The balanced equation for the formation of methanol (CH3OH) is:

2 H2(g) + CO(g)  CH3OH(g)


We’re being asked to determine at what temperature the given reaction is spontaneous. The standard free energy change of a reaction (ΔG˚rxn) is given by the following equation:



We’re given the ΔH˚f and S˚ of each reactants and products. We can use those to calculate for ΔH˚rxn and ΔS˚rxn separately.
