Question

Cu(s) + 2 Ag⁺ → Cu²⁺ + 2 Ag(s)

If the equilibrium constant for the reaction above is 3.7 x 10¹⁵, which of the following correctly describes the standard voltage, E˚, and the standard free energy change, ∆G˚, for this reaction?

1. E˚ is negative and ∆G˚ is positive.
2. E˚ and ∆G˚ are both positive.

1. E˚ is positive and ∆G˚ is negative.
2. E˚ and ∆G˚ are both negative.

is this correct

Answer 1

Yes, that seems correct.

The fact that the equilibrium constant is so large tells us that the reaction favors the products. This makes the Eºcell positive and spontaneous. A spontaneous reaction will have a negative ∆G.
