Finding K using standard potential

Postby Toru Fiberesima 1L » Tue Feb 26, 2019 9:14 am

Is there a way to use cell potential to calculate Ka without using Nernst? Can you go about this by finding Ecell, using that to find dG and then solving for K usuing -RTlnK?

The Nernst equation is mainly used for reaction mixtures not at equilibrium. If you are trying to find K using standard potential, the method you described works.
