At a particular temperature why vapour pressure of acetone is less than that of ether.

In the depression of freezing point experiment it is found that (i) The vapour pressure of the solution is less than that of pure solvent (ii) The vapour pressure of the solution is more than that of pure solvent (iii) Only solute molecules solidify at the freezing point (iv) Only solvent molecules solidify at the freezing point

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

The temperature at which the vapour pressure of a liquid becomes equal to the external pressure is its

The temperature at which the vapour pressure of a liquid becomes equal to the external pressure is its:

The liquids X and Y form an ideal solution . The mixture has a vapour pressure of 400 mm at 300 K when mixed in the molar ratio of 1: 1 and a vapour pressure of 350 mm when mixed in the molar ratio of 1:2 at the same temperature . The vapour pressures of the two pure liquids X and Y respectively are

Vapour pressure of liquid depend only on

At a given temperature total vapour pressure (in torr) of a mixture of volatile compounds A and B given by P_("total")=120-75X_(B) . Hence, vapour pressure of pure A and B respectively (in torr) are

Rectified spirit is a mixture of alcohol and water which behaves like pure liquid and boils at constant temperature. Calculate the vapour pressure of 10% aqueous solution of glucose (molecules mass 180) at 303 K. The vapour pressure of pure water at 303 K is 31.8 mm.

Pyridine is less basic than
