STANDARD Chemistry Henry's Law MCQ Question
Type: MCQ-conceptual-Medium-Class 12
According to Henry's law 'the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution'. For different gases the correct statement about Henry's constant is
A
higher the value of Kₕ at a given pressure, higher is the solubility of the gas
B
higher the value of Kₕ at a given pressure, lower is the solubility of the gas
C
Kₕ is not a function of nature of gas
D
Kₕ value for all gases is same at a given pressure.
Correct Answer
Option B
Detailed Explanation
Henry's constant (Kₕ) is inversely related to solubility. A higher Kₕ value indicates lower solubility of the gas in the liquid at a given pressure.
