The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of 20% is to 79% by volume at 298 K. The water is in equilibrium with air at a pressure of 10 atm. At 298 K , if the Henry’s law constants for oxygen and nitrogen at 298 K are 3.30 × 10 7 mm and 6.51 × 10 7 mm respectively, calculate the composition of these gases in water.
Options
- Ax(O 2 ) = 9.22×10 -5 , x(N 2 ) = 4.6 x 10 -5
- Bx(O 2 ) = 4.6 x 10 -5 , x(N 2 ) = 9.22×10 -5
- Cx(O 2 ) = 5.8 x 10 -5 , x(N 2 ) = 7.34×10 -5
- Dx(O 2 ) = 7.34 x 10 -5 , x(N 2 ) = 5.8×10 -5
Correct answer
B. x(O 2 ) = 4.6 x 10 -5 , x(N 2 ) = 9.22×10 -5
Step-by-step solution
Correct Option is : (B) x(O 2 ) = 4.6 x 10 -5 , x(N 2 ) = 9.22×10 -5
