9.2 CONDITIONS FOR EQUILIBRIUM

Equilibrium is achieved when pure reactants, pure products, or a mixture of reactants and products are first placed in a closed container, in each such case, forward and backward movement in the tank occurs at the same speed. This leads to a situation where the concentrations of reactants and products remain the same indefinitely, as long as the following physical conditions are met:

1. The concentration of reactant or product remains unchanged.
2. The temperature of the system remains constant.
3. The pressure or volume of the system remains constant.
