Question

The ratio of \( N_2 \) and \( O_2 \) gases in the atmosphere is \( 4:1 \). The ratio of the mole fractions of the dissolved gases \( N_2:O_2 \) in rain water will be approximately --------. At \( 293\,K \), \( K_H \) for Nitrogen and Oxygen in kbar units are \( 76.48 \) and \( 34.86 \) respectively.

• A. \( 3:1 \)
• B. \( 2:1 \)
• C. \( 4:1 \)
• D. \( 1:4 \)

Hint:

In Henry's law, solubility is inversely proportional to \( K_H \). A gas with lower \( K_H \) is more soluble in liquid.

Answer 1

The Correct Option is B
