R2.3 (AHL) Reaction quotient & equilibrium law
This AHL section distinguishes between reaction quotient, Q and the equilibrium constant, K. It shows how to calculate the reaction quotient from the concentrations of reactants and products at a particular time, and determine the direction in which the reaction will proceed to reach equilibrium. The equilibrium constant and Gibbs energy change, ΔG, can both be used to measure the position of an equilibrium reaction....
