One question. When does the summation term equal zero? So when is the summation of the number of moles times the chemical potential equal to zero? Thanks!

If Gibbs energy is non pv work. Then why do we say that maximum work an engine does is 20 percent of maximum work available. As engine uses pv work to make the car move?

An engine does use primarily PV (mechanical) work. The Gibbs Free Energy does contain a mechanical work term, VdP. However, at constant pressure, the VdP term (mechanical work term) is zero. There are A LOT of ways to express the energy of a system, e.g., Kinetic Energy, Potential Energy, Work, Heat, Electric work, Magnetic work, etc... and in Thermodynamics there are also lots of ways to express energy, e.g, Internal Energy, Enthalpy, Helmholtz Energy, Gibbs Energy, etc... We typically use the form of energy that is most relevant to a specific problem or system. In chemistry, the Gibbs Free energy is used so often because at constant T & P, it is then directly related to the chemical potential energy (chemical potential times the change in the number of moles / constituents).

@@JeffYarger that means Gibbs energy is not necessarily should always be under constant temperature and pressure. It's just a specific case?

EVERY TIME YOU HEAR THE WORD POTENTIAL HE MEANS POTENTIAL ENERGY. NO POTENTIAL HAS UNITS OF JOULE ... you know.

The total differential wasn't quite correct, but still a good video
