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:
Consider the following reaction:
CH3OH(g) ⇌ CO(g) + 2H2 (g)
Calculate ΔG for this reaction at 25°C under the following conditions:
PCH3OH = 0.890 atm
PCO = 0.120 atm
PH2 = 0.200 atm
Δ G = kJ
