For the pH question, I think you had to use the Van't Hoff equation, which was given on the equation sheet. This equation relates the change in the equilibrium constant with the change in temperature. Using this equation, you can find the new equilibrium constant as a result of the change in temperature and then calculate pH from there.

The Van't Hoff equation, provided on the equation sheet, was necessary for this. That being said, I did another method where I calculated the K using the relation between E cell and gibbs free energy and got the same answer, but I do not believe that that was the way you were supposed to calculate the pH since enthalpy was given.

How do you find the pH from K?

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