Delta G= Wmax
Can someone explain what Wmax means? Also why are delta G and Wmax equal at constant T and P? What is the relationship between the two?

Re: Delta G= Wmax
Wmax refers to the maximum amount of work a system can do. Delta G is the maximum work that a system can do at a given temperature and pressure. So we can equate the two.

DeltaG is the maximum amount of work a system can do at a given temperature and pressure, while WMAX is the maximum amount of work a system can do. Therefore, you can set them equal to each other.

I wrote in my notes from 2/9 that maximum cell potential is directly related to the free energy difference between reactants and products in the cell/ redox reaction.

Re: Delta G= Wmax
Wmax actually represents the maximum non-expansion work a reaction can do. Basically, an exothermic reaction will release a certain amount of energy, and this energy can be harnessed to do other kinds of work, such as power a non-spontaneous reaction.

No, at equilibrium Delta G and Ecell are equal to zero, and therefore work at equilibrium would be equal to zero. This makes sense, as at equilibrium there would be no electrons flowing between the anode and the cathode.
