We’re being asked which reaction(s) will proceed in the reverse direction?
The standard free energy change of a reaction (ΔG) is given by the following equation:
The signs of ΔG, ΔH, and ΔS at 25°C are shown below for three reactions.
Reaction ΔG ΔH ΔS
I – + +
II – – +
III – – –
Which reaction(s) will proceed in the reverse direction?
