Question

(a) In the following equilibrium

N₂O₄(g) ⇋ 2NO₂(g)

when 5 moles of each are taken, the temperature is kept at 298 K the total pressure was found to be 20 bar. Given that

(i) Find ΔG of the reaction 

(ii) The direction of the reaction in which the equilibrium shifts

(b) A graph is plotted for a real gas which follows van der waals' equation with pV_m taken on Y-axis and p on X-axis. Find the intercept of the line where V_m is molar volume.
