Consider a solution of $\displaystyle \mathrm{CO}_2(\mathrm{~g})$ dissolved in water in a closed container.
Which one of the following plots correctly represents variation of log (partial pressure of $\displaystyle \mathrm{CO}_2$ in vapour phase above water) [ $\displaystyle y$-axis] with log (mole fraction of $\displaystyle \mathrm{CO}_2$ in water) [ $\displaystyle x$-axis] at $\displaystyle 25^{\circ} \mathrm{C}$ ?
