More than one distinct microstate of a system can have a particular energy (a macrostate). the purpose of this interactive example is to ensure that you know how to deal with this fact when calculating the probability that a small system (here, a molecule) in contact with a thermal reservoir has a particular energy. let's consider a molecule that can be in one of six microstates. it exchanges energy with a thermal reservoir at a temperature t. one microstate has energy ea, two states have energy eb = 3ea, and three states have energy ec = 5ea. to simplify the numerical calculation, you may assume that the temperature is such that kbt = ea. what is the probability that the molecule has energy eb? p(eb) =
