Many pharmeceuticals are derived from piperazine. solutions of piperazine are basic (Kb1=5.38x10^-6, Kb2=2.15x10^-9). What is the pH of a 0.0185 M solution of piperazine. For this problem assume it is ok to have up to a 10 percent error in our "simplifying assumption".
The rotational constant of CO is 1.931 cm-1. Evaluate the rotational partition function (without approximation) and plot its value as a function of temperature.
