State the formula relating pressure of a gas with its mole fraction in a liquid solution in contact with it.

Define mole fraction of a solute in a solution.

At constant temperature, pressure of a gas is --------- to its volume.

With the help of Raoult's law show that total vapour pressure of a binary liquid solution varies linearly with the mole fraction of a component.

What concentration of nitrogen should be present in a glass of water at room temperature at 25^@C , a total pressure of 1 atm and mole fraction on nitrogen in air of 0.78 [ K_H for nitrogen = 8.42xx10^(-7)M//mmHg ].

State the relation between rms speed of the molecules of a gas and its temperature.

State the role of activated complex in a reaction and state its relation with activation energy.

Solution of two volatile liquids A and B obey Roalt's law. At certain temperature, it is found that when the toal pressure above a solution is 0.53 bar. The mol fraction. A in the vapour is 0.45 & other liquid is 0.65. What are the vapour pressures of the two pure liquids at the given temperature?

Give one example each of solid in a gas and liquid in gas solution.

Explain why Vapour pressure of a liquid decreases when a non-volatile solute is added to it.

Write down an expression for the pressure of a gas in terms of its mass,volume and rms velocity.
