Imagine a particle that can be in only 3 states with energies 1 eV, 2 eV, and 3 eV. The particle is in equilibrium with a reservoir at 300 K.
a) Calculate the partition function for this particle.
b) Calculate the probability of the particle being in the 2 eV state.
c) How does the probability in part (b) change if the reservoir temperature is 3000 K?
