calculating reaction Gibbs free energy

Postby Nhi Vo 3A » Sat Feb 04, 2017 10:05 pm

The reaction taking place in the silver cell used in some cameras and wristwatches in Ag2O(s) + Zn(s) --> 2Ag(s) + ZnO(s), and the cell potential when new is +1.6V. What is the reaction Gibbs free energy?

Gibbs free energy is related to E cell by this equations: ΔG = −nFEocell

Just plug in the value of Ecell and you have your answer. This equation can be found in the "How do we do that?" on page 571 of the textbook.
