Chemists always want to find ways to increase the yield of a reaction. It would appear that equilibrium is the chemist’s worst enemy! (At least when a reaction has a small equilibrium constant. Read important point 5.) Two common ways for a chemist to increase the yield of a reaction are described below. Explain why they increase the yield.
