1.	Each question given below contains STATEMENT -1 (Assertion) and STATEMENT -2 (Reason). It has four choice (a), (b), ( c ) and (d)out of which ONLY ONE is correct . Choosethe correct option as under : Statement -1 Adding inert gas to dissociation equilibrium of N_(2)O_(4)at constant pressure and temperature increases the dissociation. Statement -2. Molar concentrations of the reactants and products decrease .
Answer» (a) Statement -1 is True , Statement-2 is true , Statement -2 is the correct explanation of Statement-1 (b) Statement -1 is True , Statement -2 is not a correctexpanation of Statement -1 . (c ) Statement-1 is True, Statement -2 is False . (d) Statement -1 is False , Statement -2 is True . Solution :To Keep the pressure constant , volume WOULD INCREASE. As a RESULT , molar concentration of each reactant and product will decrease. For `N_(2) O_(4) HARR 2 NO_(2) , K = ([NO_(2)]^(2))/([N_(2) O_(4)]` To keep K constant , `N_(2)O_(4)`should decrease more.
