8.20a. A system with 100,000 molecules has two energy levels (A
and B). At first, the two energy levels are populated equally.
After a reversible process, energy level A is populated by 65% of
the molecules and the system is at 293K.
a. What is the difference in energy between the two levels?
Answer in kJ/mol with one number after the decimal point.
b. How much heat was added or removed from the system? Answer in
kJ to the nearest integer. Remember the sign definition for heat
added or removed from a system.
c. What is the change in entropy? Answer in kJ/K. Include 2
digits after the decimal point.
