1. Probable energy states for molecules at room temperature

(a) Suppose we have an system that has the following allowed electronic energy states: 0.2 eV, 2.0 eV, 3.0 eV, 10eV. What is the probability of the system to be at each of these energy states at 350K, 1000K?

(b) Suppose we have a system that has the following allowed rotational energy states: 1.30E-03 eV, 2.1E-03 eV, 3.10E-03 eV. What is the probability of populating these rotational states at 300K and 5000K?

(c) From the above analysis what rotational and electronic states are you likely to find a typical molecule in at room temperature?
