Reaction Quotient and Le Chatelier's Principle, Equilibrium, Example - Chemistry

This video explains the meaning of reaction quotient vs equilibrium constant, including definition, what happens if Q is bigger or less than K, and the difference between Q and K. You will understand how different stresses like concentration, temperature and catalysts affect the concentrations of reactants and products, the the rate of the forward and backward reaction.
