Question

Consider a solution of $$\mathrm{CO_2(g)}$$ dissolved in water in a closed container. Which one of the following plots correctly represents the variation of $$\log$$ (partial pressure of $$\mathrm{CO_2}$$ in the vapour phase above water) [$$y$$-axis] with $$\log$$ (mole fraction of $$\mathrm{CO_2}$$ in water) [$$x$$-axis] at $$25^\circ	ext{C}$$?

Accepted Answer

C. A straight line with **positive** slope and a **positive intercept** on the $$y$$-axis
