A substance shows the phenomenon of deliquescene if its vapour pressure _____that of water vapour in air .

What is the effect of temperature on the vapour pressure of a liquid?

100 g of liquid 'A' (molar mass '140 g/ mol' ) was dissolved in 1000 g of liquid 'B'. (molar mass 180 g/mol The vapour pressure of pure liquid B was found to be 500 torr. Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution, if the total vapour pressure of the solution is 475 torr.

Pick up the wrong statement: a)Deliquescent salts are highly soluble in water. b)Vapour pressure of water in hygroscopic substances in their solution state is lower than humidity of air. c)Efflorescent crystals have higher vapour pressure of water than humidity of air. d)For isotonic solution concentrations of two solutions must be always same.

The vapour pressure of pure liquids A and B are 450 and 700mm Hg respectively at 350K. Find out the composition of the liquid mixture if total vapour pressure observed is 600mm Hg.

Derive an expression for the relative lowering of vapour pressure?

Select the incorrect statements for vapour pressure of pure liquid

100 g of liquid A (molar mass 140g"mol"^(-1) ) was dissolved in 1000 g of liquid B (molar mass 180 g"mol"^(-1) ) . The vapour pressure of pure liquid B was found to be 500 torr. What will be the vapour pressure of pure liquid A and its vapour pressure in the solution respectively if the total vapour pressure of the solution is 475 torr?

Vapour pressure of liquid depend only on
