The set up of two galvanic cells is given. The value of maximum work that can be obtained from the given galvanic cell is to be calculated. Concept introduction: The species with higher reduction potential undergoes reduction at the cathode while the species with lower reduction potential undergoes oxidation at the anode. The change in Gibbs free energy is the useful amount work that can be done and negative value of Δ G ° shows that the reaction is spontaneous in nature. To determine: The value of maximum work that can be obtained from the given galvanic cell.

The table includes macrostates characterized by 4 energy levels (&) that are
equally spaced but with different degrees of occupation.
a) Calculate the energy of all the macrostates (in joules). See if they all have
the same energy and number of particles.
b) Calculate the macrostate that is most likely to exist. For this macrostate,
show that the population of the levels is consistent with the Boltzmann
distribution.
