### Nernst Equation Confusion

On the constants and equations sheet, can someone explain the difference between E = Eº - RT/nF ln Q (Nernst Equation) and E = Eº - 0.05916V/n logQ? Can someone also explain when to use each equation?

just another version of a derivation. they mean the same thing

They both mean the same thing.

They are the same, however the second equation is commonly used in questions that ask for pH to be found from the [H+]

### Re: Nernst Equation Confusion

The second equation can only be used at room temperature 298 K.

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