answer question 6 and 7 with right choice of answer.
6.  Answer :-  d) there will be no change to the equilibrium system. Since, at constant volume, addition of inert gas to the equilibrium reaction,  there is no change in concentrations of the products and reactants. Hence, no change on the equilibrium.  Note :-   at constant pressure, addition of inert gas to the equilibrium will increase the volume and hence concentration of reactant and product changes. T ...
