Calculate ΔG∘rxn and E∘cell for a redox reaction with n = 1 that has an equilibrium constant of K = 28?

Question

What would the answer be to this? Could someone work this out for me please?

ΔG∘rxn = ......kj

E∘cell = ......V

Answer 1

I gave you the formula for doing this yesterday. If you still have problems show your work so I can spot the error.
