Which of the following statements are true about an ideal solution of two volatile liquids? a. the partial pressure of each component above the liquid is given by raoult's law. b. the liquid and gaseous phases can only coexist for a single value of the pressure at a given temperature. c. an ideal solution of two volatile liquids can exist over a range of pressures that are limited by the pressure for which only a trace of liquid remains, and the pressure for which only a trace of gas remains. d. the vapor phase is always depleted in the more volatile or higher vapor pressure component in comparison with the liquid phase.

The statements that are true about an ideal solution of two volatile liquids are:

A. The partial pressure of each component above the liquid is given by Raoult's law.

C. An ideal solution of two volatile liquids can exist over a range of pressures that are limited by the pressure for which only a trace of liquid remains, and the pressure for which only a trace of gas remains.

Explanation:

The statements that are true about an ideal solution of two volatile liquids are:

A. The partial pressure of each component above the liquid is given by Raoult's law.

In ideal solutions, the total vapor pressure can be calculated based on Raoult's law, which states that:

"The partial pressure Pi of a component in a solution at a given temperature is equal to the vapor pressure of the pure substance (Pi) multiplied by its molar fraction (xi) in the solution", then:

Pi = xi · Pisaturation

where:

• Pi: Pressure of i in liquid state.

• xi: Molar fraction of component i.

• Pisaturation: Vapor pressure of component i.

The total vapor pressure (PT) of a mixture is equal to the sum of the partial vapor pressures (Pi) of each component. Then, for a mixture of two pure liquids A and B the total pressure will be:

PT = xA · PAsaturation + xB · PBsaturation

C. An ideal solution of two volatile liquids can exist over a range of pressures that are limited by the pressure for which only a trace of liquid remains, and the pressure for which only a trace of gas remains.

In an ideal solution, the vapor pressure depends linearly on the molar fraction.  The attached graph shows the linear realization mentioned for an ideal solution of two components at constant temperature.

In the graph you can see that option c is true.

i believe the answer is a

i think the answer would be reserve.
