need the correct ans asap
c) In a multicomponent solvent recovery distillation column, gas and liquid phases are in
equilibrium. The liquid mixture consists of 30 mol % pyridine (C5H5N), 30 mol % styrene
(CsHs) and the balance toluene (C7Hs) is in equilibrium with the gas mixture at 90°C and
0.5 atm. Use Raoult's law relationship to determine composition of the
gas phase (YA) mixture and partial pressure (PA) of each compound.
Raoult's law: PA = YAP = XAPA (T)
