If liquids A and B form an ideal solution then

A

The entropy of mixing is zero

B

The Gibbs free energy as well as the entropy of mixing are each zero

C

The Gibbs free energy as well as the enthalpy of mixing are each zero

D

The enthalpy of mixing is zero

Text Solution

Verified by Experts

The correct Answer is:
D
For the ideal solution, the enthalpy of mixing of the pure components to form the solution is zero.
`Delta _(mix ) H = 0, ,Delta _( mix) V =0`

Two liquid A and B form an ideal solution at temperature T. When the total vapout pressure above the solution is 400 torr , the mole fraction of A in the vapour phase is 0.40 and in the liquid phase 0.75. What are the vapour pressure of pure A and pure B at temperature T?

Two liquids A and B form an ideal solution such that p_(A)^@ = 700 mm and p_(B)^@ = 300 mm . A small amount of solution is vapourized and the vapour condensed (at equilibrium). The condensate has equilibrium vapour pressure of 500 mm (at same temperature). Find the composition of the original solution.

Two liquids, A and B, form an ideal solution. At the specified temperature, the vapour pressure of pure A is 200 mmHg while that of pure B is 75 mmHg. If the vapour over the mixture consists of 50 mol percent A, what is the mole percent A in the liquid ?
