Chemistry 2710 Spring 2000 Quiz 9

Name:

We saw in class that the typical spacings between electronic, vibrational and rotational levels are, respectively, 10^-18, 10^-20 and $10^{-22}\,\mathrm{J}$. For each of these spacings, calculate the temperature at which the ratio of the populations in two adjacent energy levels is $\frac{1}{10}$.

Note: $k = 1.381\times 10^{-23}\,\mathrm{J/K}$
