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
