More than one distinct microstate of a system can have a particular energy (a macrostate). The purpose of this interactive examp
le 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) =

Explanation: For the first case we have to use the Balmer series for the hydrogen when the atom falls from the n = 3 to the n = 2. So for the second transtions for the hydrogen we use the Paschen serie. To do the calculation we need to know the Ryberg constant that is equal to 1.097 * 10^7 m^-1. In the attach is shown the expression for spectral series used for calculation.
