For an ideal binary solution, how does total vapour pressure vary with the mole fraction of one component?
AExponentially
BThrough a minimum
CThrough a maximum
DIn a linear way
Answer & Solution
Correct answer: D. In a linear way
Since p(total) = p1(pure) + (p2(pure) - p1(pure)) x2, the total vapour pressure is a straight-line function of x2.
