Question
PA and PB are the vapour pressure of pure liquid components. A and B, respectively of an ideal binary solution. If xA represents the mole fraction of component A, the total pressure of the solution will be
Options
A.pB + xA (pA - pB)
B.pA + xA (pB - pA)
C.pA + xA (pA - pB)
D.pB + xA (pB - pA)
Solution
PTotal = pA . xA + pB . xB
xB + xA = 1
xB = 1 - xA
PTotal = pA . xA + pB(1 - xB)
