Raoult's Law

Raoult's law is given by:


Where:
p
i: pressure of component i
x
i: mole fraction in the solution
: vapor pressure of the pure substance i

In a solution with two liquids A and B, if no gas are present, the total vapor pressure is given by:

P
tot = PA + PB

Where:
P
A: vapor pressure of liquid A
P
B: vapor pressure of liquid B

For an ideal solution of liquids A and B, which obeys Raoult's law over the full range of composition. The total pressure is given by:



Which is equal to:
