Question

What happens to the vapor pressure if we mix two volatile liquids (both have measurable vapor pressure)?

PTotal = PA + PB = XA P°A + XB P°B



A.
Vapor pressure is smaller than vapor pressure of either pure liquid.
B.
Vapor pressure is larger than vapor pressure of either pure liquid.


C.
Vapor pressure is between vapor pressures of the pure liquids.

Answer 1

Vapor pressure is between vapor pressures of the pure liquids.

Step-by-step explanation:

Vapor pressure is between vapor pressures of the pure liquids.
