A reaction quotient is the ratio between the concentration of products to the concentration of reactants at any point of the reaction. This means that the point when a reaction quotient is measured does not guarantee that the reaction is in equilibrium.
On the other hand, an equilibrium constant is the ratio between the concentration of products to the concentration of reactants at the equilibrium point. This means that when the ratio between reactants and products in a reaction reaches the equilibrium constant, the reaction is in equilibrium.
Hi, thank you for your question.
