NEET 2024 · ChemistryPrevious Year Question
The Henry's law constant () values of three gases (A, B, C) in water are 145, and 35 kbar, respectively. The solubility of these gases in water follow the order:
Answer: (A) B > C > A. \textbf{Answer:} (A) B > C > A \textbf{Solution:} Henry's law states , where is the mole fraction (solubility) of the gas.
- A.B > C > A✓
- B.A > C > B
- C.A > B > C
- D.B > A > C
Correct Answer
(A) B > C > A
Solution & Explanation
\textbf{Answer:} (A) B > C > A \textbf{Solution:} Henry's law states , where is the mole fraction (solubility) of the gas. At a fixed partial pressure, solubility is inversely proportional to : . Thus a smaller means greater solubility. Ordering the values: A (145) > C (35) > B (). The solubility order is the inverse: B > C > A.
