plz do part A and i will repost for Part B
![2.6 Experimental measurements of Vaughan and Collins [Ind. Eng.
Chem., 34, 885 (1942)] for the propane-isopentane system at 167°F
and 147 psia show for propane a liquid-phase mole fraction of 0.2900
in equilibrium with a vapor-phase mole fraction of 0.6650. Calculate:
(a) The K-values for C3 and iC5 from the experimental data.
(b) Estimates of the K-values of C3 and iC5 from Raoult's law
assuming vapor pressures at 167°F of 409.6 and 58.6 psia,
respectively.
Compare the results of (a) and (b). Assuming the experimental values
are correct, how could better estimates of the K-values be achieved?
To respond to this question, compare the rigorous expression
K₁ = YiLiL/Oiv to the Raoult's law expression K; = P{/P.
