# Factors Influencing Equilibrium Concentration

The effect of temperature, pressure and adding reactants or products are described under the heading of Le Chatelier’s principle. The effect of inert gas addition is described here.

E.g.

(i)     There is no effect of addition of inert gas if $\Delta n = 0.$

(ii)     At constant pressure if $\Delta n > 0$ or (+) ve then on addition of inert gas the concentration of products increases while that of reactants decreases.

(iii)       At constant volume if $\Delta n > O$ or (+) ve then on addition of inert gas there is no change in concentration of the reactants or products.
