Azeotropic Mixtures

Q.

A mixture of $N_2$ and $C{O}_2$ at one atm pressure contains 56% by weight of $N_2$ . Partial pressure of $N_2$ in the mixture will be:

a)0.56 atm

b)0.44 atm

c)0.677 atm

d)0.33 atm

Q.

The liquid mixtures which distill with a change in composition are called

1. azeotropic mixtures

2. equilibrium mixtures

3. zeotropic mixtures

4. nonequilibrium mixtures

Q. 17. 18 L mixture of N2 & H2 gives maximum 6L of NH3 at same temp and pressure then what will be the ratio of N2 and H2 initially??

Q. how to compare the boiling point among AsH3, SbH2, BiH2, NH

Q. $P_{\left(A\right)}^o$ = 60 mm of Hg and $P_{\left(B\right)}^o$ = 45mm of Hg. If 1 mol of A and 2 mol of B are mixed, the solution forms an azeotropic mixture with a minimum boiling point, then mole fraction of A in its vapour phase above the solution will be

1. $\frac{2}{5}$
2. $\frac{3}{5}$
3. $\frac{2}{3}$
4. $\frac{1}{3}$

Q. At ${35}^{o}C$, the vapour pressure of $C{S}_{2}is512mmHg$ and that of acetone is $344mmHg$. A solution of $C{S}_2$ in acetone has a total vapour pressure of $600mmHg$. The false statement amongst the following is
(JEE MAIN 202)

1. A mixture of 100 mL $C{S}_2$ and 100 mL acetone has a volume < 200 mL
2. $C{S}_2$ and acetone are less attracted to each other than to themselves
3. Heat must be absorbed in order to produce the solution at $35°C$
4. Raoult's law is not obeyed by this system

Q. $P_{\left(A\right)}^o$ = 60 mm of Hg and $P_{\left(B\right)}^o$ = 45mm of Hg. If 1 mol of A and 2 mol of B are mixed, the solution forms an azeotropic mixture with a minimum boiling point, then mole fraction of A in its vapour phase above the solution will be

1. $\frac{2}{5}$
2. $\frac{3}{5}$
3. $\frac{2}{3}$
4. $\frac{1}{3}$
