The Equilibrium Constant

Mr. Anderson explains the concept of the equilibrium constant (K) using phosgene as an example. He discusses how K indicates the ratio of products to reactants at equilibrium and demonstrates this with a PHET simulation. The video covers how to calculate K, the effect of temperature on K, and the implications of different K values on chemical reactions. A large K value means more products, while a small K value indicates more reactants. The video concludes with a summary of how K can predict chemical concentrations at equilibrium.
