I have been trying to find an expression for the work done by a voltaic cell online to no avail. My strategy for coming up with one was to rework the nernst equation to give the voltage difference as a function of the charge that has been transferred and then to integrate the function with respect to charge. My answer seems to make sense as it starts with nFE₀ and is followed by a bunch of correction terms. If anyone could show me a formula for this or verify that my approach is viable it would be greatly appreciated.

Thanks,
Jacob

You can try to approach the problem from thermodynamic side - what is free energy definition?

Well, from basic physics, P = IV where P is power (work/time), I is current, and V is the emf of the cell.

As far as I understand, that's what he did, just taking into account fact that voltage changes with the reaction progress.

From a thermodynamic side i can set dG=nFE(X)dX where E(X) is the emf of the cell as a function of a product and dX is a differential product change right? I'll have to try this to see how it compares to my first one. Thanks.
