1. A simple system has three microstates: state 1 with energy u1 = 0, state 2 with energy u2 = +2.5kJ/mol, and
state 3 with energy u3 = +5.0kJ/mol.
a) Find the partition function.
b) Find the absolute probabilities, P1, P2, and P3 of finding states 1, 2, and 3, for T = 300 K.
c) Use a computer to plot the probabilities vs. Temperature from T=100K to 1000K.
