Calculating the Equilibrium Constant

In order to experimentally determine the equilibrium constant of a reaction, measuring the concentration or partial pressure of the reactants and products can be done in many ways. These can include titration or spectroscopy for concentration and by isolating the different gasses in a container to measure their partial pressures individually. On the AP Exam, you may need to identify these methods, but will not be asked on how they work in detail greatly.
