Question:

Assuming Raoult's law to apply to the system n-pentane (1) In-hcptand(2),
(a) What arc the values of x1 and y1 at t = 55°C und P = 1/2 (P1sat + P2sat)? For these conditions plot the fraction of system that is vapor V vs. overall imposition z1.
(b) For t = 55 C and z1 = 0.5, plot P. x1, arid y1 vs. V.
