We’re being asked to determine the standard free energy change (ΔG) at 25 ˚C for the given reaction:

CH3OH(g)  CO(g) + 2 H2(g)

Because of the double-arrows, we can say that this is an equilibrium reaction.

We are given the following equilibrium pressures of each compound:

PCH3OH = 0.890 atm

PCO = 0.120 atm

PH2 = 0.200 atm

Recall that ΔG and K are related to each other:

$\overline{){\mathbf{\Delta G}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{-}}{\mathbf{RTlnK}}}$
