### 5G.15 (7th Ed.)/ 11.17 (6th ed.)

Can someone explain why the solution manual is using the formula deltaG=-RTlnK + RTlnQ instead of deltaG= deltaGnot + RTlnQ.

Since you're given the value of K in this particular problem, rather than look up the Gibbs free energy of formation values, you can just substitute in the -RTlnK for greater convenience in your calculations.

Return to “Work, Gibbs Free Energy, Cell (Redox) Potentials”
