Which two values for ΔG and E°cell correctly indicate a spontaneous reaction?

ΔG = - 295kJ, E°cell = + 1.53 v

ΔG = - 295kJ, E°cell = - 1.53 v

ΔG = + 295kJ, E°cell = - 1.53 v

ΔG = - 1.53v, E°cell = + 295 kj

Well as an spontaneous reaction will have a negative gibbs free energy (delta g) and a positive e cell and also the E cell is also measured in V, then your answer is the first one: ΔG = - 295kJ, E°cell = + 1.53 v. Hope this works
