Solution Summary: The author explains that the shift of equilibrium is to be predicted for given options, based on Le Chatelier's principle.
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.

In an experiment, the viscosity of water was measured at different
temperatures and the table was constructed from the data obtained.
a) Calculate the activation energy of viscous flow (kJ/mol).
b) Calculate the viscosity at 30°C.
