Calculate Henry's law constant if solubility of gas in water at 25^ C is 5.14 10⁻⁴ ~mol dm ⁻³ and partial pressure of the gas is 0.75 bar above solution.
Options
- A6.85 10⁻⁴ ~mol dm ⁻³ bar ⁻¹
- B5.14 10⁻⁴ moldm ⁻³ bar ⁻¹
- C1.028 10⁻⁴ ~mol dm ⁻³ bar ⁻¹
- D1.371 10⁻⁴ ~mol dm ⁻³ bar ⁻¹
Correct answer
A. 6.85 10⁻⁴ ~mol dm ⁻³ bar ⁻¹
Step-by-step solution
According to Henry's law, S = K _ H P aligned K _ H & = S P = 5.14 10⁻⁴ ~mol dm ⁻³ 0.75 bar & =6.85 10⁻⁴ ~mol dm ⁻³ bar ⁻¹ aligned
