Chemical Equilibrium

• Chemical equilibrium is the state of a system in which the rate of the forward reaction is equal to the rate of the reverse reaction
• Chemical equilibrium is also known as dynamic equilibrium
• Equilibrium between reactants and products is achieved regardless of weather the reaction starts with the reactants or products
• The forward and reverse reactions continue to occur even after equilibrium has been reached
• 1. The system must be closed, meaning no substances can enter or leave the system
• Equilibrium is a dynamic process even without seeing the process, the forward and reverse reactions are taking place
• The rates of the forward and reverse reaction must be equal
• The amout of reactants and prducts do not have to be equal
• The equilibrium constant is the ratio of the mathematical products of the products of a reaction to themathematical product of the concentrations of the reactants of the reaction
• Le Chatelier's Principle is the principle when a stress is applied to a chemical system at equilibrium, the system will move to counteract the stress
• Le Chatelier's is also known as the equilibrium law
• Le chatelier's principle predicts the effect of changes on the system
• Le chatelier'sprinciple states that a system at equilibrium that is subjected to a change responds to the change to partly counteract the change and establish a new equilibrium
• Disturbing a system at dynamic equilibrium shifts the equilibrium in the direction that counteracts the change
• The three factors that affect Le Chatelier's Principle are: Pressure, Volume, Temperature
• Concentration: If you add more reactants, there will be more products
• Concentration: If you add more product, there will be more reactant
