Question

Which shows the correct relationship?

A.) Eo cell > 0 = nonspontaneous reaction
B.) Eo cell > 0 = spontaneous reaction
C.) Eo cell = 0 = nonspontaneous reaction
D.) Eo cell < 0 = spontaneous reaction

Answer 1

If,
Eo is positive the reaction is spontaneous
Eo is zero then it is in equilibrium
Eo is negative the reaction is spontaneous to the reverse. Hence it is not spontaneous for the forward reaction.
therefore I think it is B

Answer 2

Spontaneous = G<0

Delta G = -nFE

E cell would need to be positive for delta g to be <0 and spontaneous.
