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:

$\boxed{\mathbf{∆}\mathbf{G}\mathbf{ }\mathbf{=}\mathbf{ }\mathbf{∆}\mathbf{H}\mathbf{ }\mathbf{-}\mathbf{ }\mathbf{T}\mathbf{∆}\mathbf{S}}$
