Tyson Wolfe · Answer 1

Reaction A to B is feasible and exothermic, C to B is not feasible and would be endothermic, given this, the reaction that is feasible is B to C, because the opposite direction of the reaction changes the sign of ΔG and ΔH.

Explanation:

When ΔG 0, the reaction cannot occur.

When ΔH 0, it meas that the reaction is endothermic, so it needs energy to be feasible.
