Question

Match the following column and correct options.
$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \left(a\right)& \text{Raoult's law}& \left(p\right)& \text{Effect of pressure on solubility of gas in liquid}\\ \left(b\right)& \text{Henry's law}& \left(q\right)& \frac{P^o-P_s}{P^o}=X_B\\ \left(c\right)& \text{Ethyl alcohol + Water}& \left(r\right)& \text{Ideal solution}\\ \left(d\right)& \text{Benzene +Toluene}& \left(s\right)& \text{Azeotropic mixture}\end{array}$

• A. $a\to p,b\to q,c\to s,d\to r$
• B. $a\to q,b\to p,c\to s,d\to r$
• C. $a\to q,b\to p,c\to r,d\to s$
• D. $a\to p,b\to q,c\to r,d\to s$

Answer 1

The correct option is B $a\to q,b\to p,c\to s,d\to r$

$a\to q\to$Raoult's law states that relative lowering of vapour pressure is directly proportional to the mole fraction of solute. $\left(\frac{P^o-P_s}{P_s^o}\right)=X_B$

$(b\to p)\to P=K_{\pi }{X}_B$ (Henry's law )

$(c\to s)\to$ Azeotrotic mixture deviates from ideal solutions

$(d\to r)\to$ For ideal solutions, $D_{mix}^r=0$

$D_{mix}^r=0$
