Le Chatelier's Principle

• Le Chatelier's Principles, also known as the equilibrium law, are used to predict the effect of some changes on a system in chemical equilibrium (such as the change in temperature or pressure). 
• The only way for equilibrium to accept more reactants is to increase product formation.
• The forward reaction is favoured when the concentration of the reactant is increased.
• The backward reaction is favoured when the concentration of the reactant decreases, the equilibrium of the reaction shift towards the production of reactants, and the concentration of the reactants is more.
• • If a reaction is exothermic, increasing the temperature will cause the K value to decrease.
