An ideal solution has equal mol-fractions of two volatile components A and B in the vapour above the solution, the mol-fractions of A and B.

Which of the following has maximum vapour pressure at a given temperature?

Two liquids X and Y form an ideal solution. At $$300$$K, vapour pressure of the solution containing $$1$$ mol of X and $$3$$ mol of Y is $$550$$ mm Hg. At the same temperature, if $$1$$ mol of Y is further added to this solution, vapour pressure of the solution increases by $$10$$ mmHg. Vapour pressure (in mm Hg) of X and Y in their pure states will be ________ respectively.

If you are given Avogadro's number of atoms of a gas $$X$$. If half of the atoms are converted into $$X_{(g)}^+$$ by energy $$\Delta H$$. The IE of $$X$$ is :

What is the density of wet air with $$75\%$$ relative humidity at $$1$$ atm and $$300$$ K? 

Under $$3$$ atm, $$12.5$$ litre of a gas weighs $$15$$ gm. What will be the average speed of gaseous molecules?

A glass container is sealed with a gas at $$0.800$$ atm pressure and at $$25^o$$C. The glass container sustain pressure of $$2$$ atm. Calculate the temperature to which gas can be heated before bursting the container.

A sample of water gas contains $$42\%$$ by volume of carbon monoxide. If the total pressure is $$760$$ mm of Hg, the partial pressure of carbon monoxide is :

If the pressure of $$N_2$$ and $$H_2$$ mixture in a closed apparatus is $$100$$ atm and $$20\%$$ of the mixture reacts then the pressure at the same temperature would be?

The vapour pressure of two liquids $$P$$ and $$Q$$ are $$80$$ torr and $$60$$ torr respectively. The total vapour pressure obtained by mixing $$3$$ mole of P and $$2$$ mole of $$Q$$ would be:
