Try to keep your balance! The episode starts with an analogy of villagers commuting from Moleville to Chemtown (0:59). Tying it to a chemical reaction, we define equilibrium as the point where the rate of the forward and the rate of the reverse reaction are the same (1:43). To determine if, at equilibrium, a reaction has more reactants or products, we can calculate the equilibrium constant, capital K (3:59) and write the equilibrium expression (4:34). The magnitude of K tells us if a reaction favors the products or the reactants (5:35). To determine if a reaction is at equilibrium, we can calculate Q (6:12).
Question (8:14): The equilibrium constant for a known reaction is K = 150. What would the value for K’ be if you’d reverse the reaction at the same temperature?
