Question 14.51

For this question it has you analyze a concentration cell of Ag--> Ag+ +e- where the anode has a concentration of .005 mol/L of Ag+ and the cathode has a concentration of .15 mol/L, and it asks what is the maximum work this cell can perform per mole of Ag. I used the Nerst equation and I keep coming out with delta G equaling -2721 J/mol which is not the correct answer.

Re: Question 14.51

For this problem, you solve for Ecell, using this formula for the Nernst equation: Ecell=Eocell-(0.025693V/n)lnQ. Then substitute that value in for deltaG= -nFEcell.

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
