What is Henry's law constant if solubility of a gas in water at 298 ~K and 1 bar pressure is 7 10⁻⁴ ~mol ~L ⁻¹
Options
- A2.0 10⁻⁵ ~mol ~L ⁻¹ bar ⁻¹
- B7.0 10⁻⁴ ~mol ~L ⁻¹ bar ⁻¹
- C3.5 10⁻³ ~mol ~L ⁻¹ bar ⁻¹
- D3.1 10⁻⁵ ~mol ~L ⁻¹ bar ⁻¹
Correct answer
B. 7.0 10⁻⁴ ~mol ~L ⁻¹ bar ⁻¹
Step-by-step solution
Solubility = K _ H pgas 7 10⁻⁴ ~mol ~L ⁻¹= K _ H 1 bar K _ H =7 10⁻⁴ ~mol ~L ⁻¹ bar ⁻¹
