Discuss the concept of vapour pressure.

Vapour pressure of pure water at 298 k is 23.8 mm Hg. Calculate the lowering of vapour pressure caused by adding 5g of sucrose in 50 g of water.

What is relative lowering of vapour pressure ?

What is relative lowering of vapour pressure ?

What is the initial effect of the change on vapour pressure ?

What is the relation between vapour pressure of a liquid and its boiling point ?

Mercury has almost no vapour pressure. Why?

Discuss the effect of pressure and temperature on the adsorption of gases on solids.

Compare the lowering of vapour pressure of equimolar calcium bromide and glucose in aqueous solutions.

Assertion : For two solutions, 0.1m aqueous solution of glucose and 0.1 m urea in benzene, the lowering of vapour pressure is same. Reason : Vapour pressure is always lowered when volatile solute is added to water
