Consider a system in thermal and diffusive contact with a reservoir. Treat the reservoir as ideal gas of particles at temperature τ . The system can be in either of the following three states: unoccupied with energy zero, occupied with energy zero (ground state), and occupied with energy ∆ (excited state). (a) Calculate the thermal average occupancy of the ground and excited sates. (b) Find the gas pressure at which the average occupancy of the system is 1/2. (c) Calculate...

Dimoglobin as a case study in cooperativity.
Note that each binding site can be occupied,
, or unoccupied,
, and that a parameter J describes the cooperativity between the O2
molecules when both states are occupied (i.e., the energy is not
just the sum of the individual binding energies).
a) Write down the weights (Gibbs factors) for each of the
different states for the dimoglobin system shown in Figure 2.
b) What is the formula that describes the energy of...

2. This problem focuses on a system that contains two indistinguishable bosons. If there are two energy levels available for each of them, then the list of possible states will look like the list in the table in Problem 1, except that the two-particle states numbered 2 and 3 are not different states, in this case. There is only one state that has one of the bosons in ε1 and one in ε2, because the bosons cannot be told apart....
