Spontaneous cell reaction

Postby Jaira_Murphy_2D » Sun Feb 24, 2019 11:53 am

After writing the corresponding cell reaction using the cell diagram how can you tell if the cell reaction is spontaneous as written?
(If the problem only tells you that the cell potential is positive)

A positive cell potential indicates the reaction is spontaneous as written for the given conditions.

Because the equation is delta G = -nFE, a positive cell potential (or E value) results in a negative delta G, and thus a spontaneous reaction.
