Question

A gaseous mixture of A, B and C is passed through water. The gaseous mixture B and C remains. If this
gaseous mixture of B and C is subjected to sudden expansion followed by application of high pressure,
B liquifies leaving behind C. Identify the set of gases
(1) SO, NO,0, (2) CI, SO, H,
COCO.N (4) NHN, H,​

Answer 1

Answer 2

The correct option is $NH_3 , N_2 , H_2$

Explanation:

• Option (4) , $NH_3 , N_2 , H_2$ is the correct option.
• When this mixture of gases is dissolved in water , $NH_3$ , dissolves in water . Since both ammonia and water are polar, they dissolve. However a gaseous mixture of $N_2$ and $H_2$ remains.
• This gaseous mixture is then subjected to sudden expansion followed by high pressure. $N_2$ liquifies as the pressure is suddenly increased. This happens due to the ideal gas law $PV = nRT$. Once an appropriate value of $P$/$V$ is reached , the gas liquifies.
