QUESTION 5 A system consists of a large number of identical molecules at equilibrium. Each molecule can be in one of a ladder of energy levels. As shown in the diagram below, the energy levels are uniformly spaced, and the difference in energy between adjacent energy levels is 1 kgT. Shown below are two instantaneous \"snapshots\" of the energies of three of the molecules, which are labeled 1, 2 and 3. A (A) Assuming that the molecules are independent and the systems are at equilibrium (i.e., the Boltzmann distribution is valid), what is the probability of seeing molecule 1 in the O level relative to the probability of seeing molecule 3 in the 3 kgT energy level, as shown in A? (B) Assuming again that the molecules are independent and at equilibrium, what is the relative probability of seeing molecules 1,2 and 3 simultaneously in the energy levels shown in A, versus the probability of seeing them simultaneously in the energy levels shown in B? That is, calculate: probability of situation A probability of situation B Show all the steps of your calculation
