Nernst Equation Confusion

Postby Clarissa Cabil 1I » Wed Mar 13, 2019 4:45 pm

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?

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

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