Current Question (ID: 18068)

Question:

$\text{Points A and B in the below-mentioned graph represent, respectively:}$

Options:

1. $\text{Partial pressures of first and second components}$
2. $\text{Vapour pressures of the pure second and first components}$
3. $\text{Partial pressures of second and first components}$
4. $\text{Vapour pressures of the pure first and second components}$

Solution:

$\text{Hint: Pressure at } x=1 \text{ is pure vapour pressure.}$ $\text{From the graph, it is clear that, left to right in } x\text{-axis concentration of the first component decreases and from right to the left concentration of the second component decreases.}$ $\text{When the mole fraction of the first component is 1, then pressure is exerted by the pure first component.}$ $\text{Same for the second component. Hence, A and B represent the vapour pressures of the pure first and second components}$
