Question

Calculate the standard free-energy change for the following reaction at 25 °C. Standard reduction potentials can be found here.

2Au^3+ (aq) + 3Zn (s) <--> 2Au (s) + 3Zn^2+(aq)

Can someone help me with this?

If you have the reduction potentials I can help you, I need them to solve this.

balance the half-reactions to get the number of eletrons transferred (n), and calculate the standard cell potential using the values you have, then plug into:

$$\Delta G^0 = -nFE^0$$
