In the reaction $${ N }_{ 2 }+{ 3H }_{ 2 }\longrightarrow { 2H }_{ 3 }$$, ratio by volume of $${ N }_{ 2 },{ H }_{ 2 }$$ and $$ { NH }_{ 3 }$$ is $$1:3:2$$. This illustrates law of :

At $$100^oC$$ and 1 $$atm$$ if the density of the liquid water is 1.0 $$g cm^{-3}$$ and that of water vapour is 0.0006 $$g \:cm^{-3}$$, then the volume occupied by water molecules in 1 $$L$$ of steam at this temperature is:

Which of the following is not a correct postulate of kinetic theory of gases?

The total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture, known as___________

$$224\,\, cm^3$$ of ammonia undergoes catalytic oxidation in presence of $$Pt$$ to give nitric oxide and water vapour. The volume of oxygen required for the reaction is:

Vapour pressure of a solvent containing nonvolatile solute is_________.

Four $$1$$ liter flasks are separately filled with the gases $$H_2, He, O_2$$ and $$O_3$$ at the same temperature and pressure. The ratio of total number of atoms of these gases present in the different flask would be:

The vapour pressure of a dilute solution of a solute is not influenced by:

Dalton's law of partial pressure is not applicable to:

Under the same conditions, two gases have the same number of molecules. They must:
