If $${X_A}$$ and $${X_B}$$ represent mole fraction in liquid phase while $${y_A}$$ and $${y_B}$$ represent mole fraction in vapour phase in binary solution. Which of the following statements is/are correct?

Henry's law constant K of $$CO_{2}$$ in water at $$20^{\circ}C$$ is $$3.0\times 10^{-2}molL^{-1}atm^{-1}$$. Calculate the mass of $$CO_{2}$$ present in 100 L of soft drink bottled with a partial pressure of $$CO_{2}$$ of 4 atm at the same temperature

Two liquids A & B form an ideal solution. What is the vapour pressure of solution containing 2 moles of A and 3 moles of B at 300 K? [Given: At 300 K, Vapour pr. of pure liquid A $$\left( P\begin{matrix} 0 \\ A \end{matrix} \right) $$=100 torr, Vapour pr. of pure liquid B $$\left( P\begin{matrix} 0 \\ B \end{matrix} \right) $$=300 torr]

According to kinetic theory of gases:

1.2 L of oxygen at a constant pressure of 2.00 atm was kept in a cylinder and provided 10.00 K cal of heat. The volume of oxygen increases to 1.8 L. The value of $$ \Delta E $$ is

Find the slope of the curve plotted between $$\mathrm { P }$$ Vs $$T$$ for closed container of volume $$2$$$$\mathrm { L }$$ having same moles of gas:

The law which suggests $$n_1 = n_2$$ for two solutions at same temperature and pressure is 

An ideal solution contains two volatile liquids $$A (P^0=100 \ torr)$$. If the mixture contains 1 mole of A and 3 moles of B, the total vapour pressure of distillate is:

An ideal gas obeying kinetic theory of gases can be liquified, if?

In a mixture of $$A$$ and $$B$$, having vapour pressure of pure $$A$$ and pure $$B$$ as $$400mm\, Hg$$ and $$600mm\, Hg$$ respectively, mole fraction of $$B$$ in liquid phases is $$0.5$$. Calculate total vapour pressure and mole fraction of $$A$$ and $$B$$ in vapour phases.
