Study Notes
Equilibrium State
- The state in which the rates of the forward and reverse reactions are equal is called equilibrium.
Factors Affecting Equilibrium
- The position of equilibrium in a chemical reaction is not affected by the concentration of reactants or products.
Effect of Pressure on Equilibrium
- When the pressure is increased in a reaction involving a decrease in the number of moles of gas, the equilibrium position shifts to the left (towards the reactants).
