1.	In which of the following reactions, the equilibrium reamins unaffected on addition of small amount of argon at constant volume?A. `H_(2(g))+I_(2(g))hArr2HI_((g))`B. `PCl_(5(g))hArrPCl_(3(g))+Cl_(2(g))`C. `N_(2(g))+3H_(2(g))hArr2NH_(3(g))`D. The equilibrium will remain unaffected in all the three cases.
Answer» Correct Answer - D If the volume is kept constant and an inert gas such as argon is added which does not take part in the reaction, the equilibrium remains undisturbed.
