How to Approach the Analysis of an IR Spectrum
In trying to analyze the spectrum of an unknown, you should concentrate your first efforts towards determining the
presence (or absence) of a few major functional groups. The C=O, OH, NH, CO, C=C, CC, CN and

Consider:
At equilibrium, the rates of the forward and reverse reactions are equal.
How the equilibrium is established is not relevant. Once equilibrium is
established, it is impossible to tell whether we started with separate
