The variation of solubility with temperature $T$ for a gas in a liquid is shown by the following graphs. The correct representation is:

The partial pressure of ethane over a solution containing $6.56 \times 10^{-2} \ g$ of ethane is $1 \ bar$. If the solution contains $5.00 \times 10^{-2} \ g$ of ethane,then what shall be the partial pressure of the gas (in $bar$)?

Which of the following ionic solids exhibits a decrease in its solubility in water with an increase in temperature?

Henry's law constant for the solubility of $N_2$ gas in water at $298\, K$ is $1.0 \times 10^5\, atm$. The mole fraction of $N_2$ in air is $0.6$. The moles of $N_2$ from air dissolved in $10$ moles of water at $298\, K$ and $5\, atm$ pressure is

What is the solubility of oxygen gas in $100 \, cm^3$ of water at $293 \, K$ (in $, cm^3$)?

If the $K_{H}$ values for $Ar_{(g)}$,$CO_{2_{(g)}}$,$HCHO_{(g)}$ and $CH_{4_{(g)}}$ respectively are $40.39$,$1.67$,$1.83 \times 10^{-5}$ and $0.413$,then identify the correct increasing order of their solubilities.
