Q 2518178009.     (a) In the following equilibrium
N_2O_4(g) ⇋ 2NO_2 (g)
when 5 moles of each are taken and the temperature is kept at 298 K, the total pressure was found to be 20 bar.
Given that

DeltaG_f^o (N_2O_4) = 100 kJ

Delta_f^o (NO_2) = 50  kJ

(i) Find DeltaG of the reaction.
(ii) The direction in which the equilibrium of the reaction shifts.

(b) A graph is plotted for a real gas which follows van der Waal 's equation with P V, taken on y-axis and P on x-axis. Find the intercept of the line where V,. is molar volume.
