What is an ideal solution? Draw the vapour pressure curve for the mixtrure of two liquids wwhich shows positive devaition from Raoults law.

A binary liquid (AB) shows positive deviation from Raoult's law when

Identify the mixture that shows positive deviation from Raoult's law.

What si Raoult law for vapour pressure of a solution. Give an example of positive deviation or Raoult law.

Two liquids A and B form an ideal solution. The ratio of vapour pressures of pure liquids A and B are 3: 5. If the mole fraction of A in the liquid solution at equilibrium with vapours is 0.4, then the mole-fraction of B in the liquid is

At 40^@C , the vapour pressure of pure liquids, benzene and toluene, are 160 mm Hg and 60 mm Hg respectively. At the same temperature, the vapour pressure of an equimolar solution of the two liquids, assuming the ideal solution should be

Two liquids A and B form an ideal solution. What is the vapour pressure of solution containing 2 moles of A and 3 moles of B at 300 K? [Given : At 300 K, vapour pressure of pure liquid A (p _A^0) = 100 torr and vapour pressure of pure liquid B (p _B^0) = 300 torr]

Two liquids X and Y on mixing form an ideal solution. At 30^@C , the vapour pressure of the solution containing 3 mol of X and 1 mol of Y is 550 mm Hg. But when 4 mol of X and 1 mol of Y are mixed, the vapour pressure of the solution thus formed is 560 mm Hg. What would be the vapour pressure of pure X and Y at this temperature?

This question has statement I and II. Of the four choices given after the statements, choose the one that best describes the two statements. Statement - I : If a liquid solute more volatile than the solvent is added to the solvent, the vapour pressure of the solution is greater than vapour pressure of pure solvent. Statement -II : Vapour pressure of solution is equal to vapour pressure of solvent.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I: Helium shows positive deviation from ideal behaviour Statement - II: Helium is a noble gas.

Two liquids A and B form an ideal solution. At 300 k, the vapour pressure of a solution containing 1 mole of A and 3 moles of B is 550 mm of Hg. At the same temperature, if one mole of B is added to this solution, the vapour pressure of the solution increases by 10 mm of Hg. Determine the vapour pressure of A and B in their pure states.
