Effect of Inert Gas Addition
In a system at equilibrium, where a particular chemical reaction balances products and reactants, adding an inert gas like argon will not shift the position of equilibrium. This is because the inert gas does not take part in the chemical reaction, thus its introduction at constant volume does not change the partial pressures of the reactants or products involved.
When the volume is kept constant, the increase in total pressure does not imply a change in the concentration of the reacting species involved. The equilibrium constant expression remains unchanged, implying that the dynamics of the system remain stable as long as there are no alterations to the concentrations of the participants in the reaction.
This principle is important in understanding how gases interact in chemical processes, particularly in industrial applications where controlling the environment around a reaction is crucial for optimizing yields and efficiencies.
