Define extent of reaction. Derive the relationship between mole fraction of
components taking part in a reaction and extent of reaction.

With neat diagram explain the effect of pressure on vapour liquid equilibrium
involving a partially miscible liquid phase.

Determine the maximum percentage of ethane that may get dehydrogenated to
ethylene at 750 [< and 5 bar, by the reaction CoH. (2) —-+» (274 (£) + 72 (2). The
standard free energy of the reaction at 750 K is 42.593 kJ. What will be the

conversion if the pressure is reduced to 0.5 bar?
