A gas X is dissolved in water at 2 bar pressure. Its mole fraction in the solution is 0.02 . Find the mole fraction of water in the solution when the pressure of the gas is doubled at the same temperature.

Options

  1. A0.04
  2. B0.98
  3. C0.96
  4. D0.02

Correct answer

A. 0.04

Step-by-step solution

Pressure, p=2 bar Mole fraction, aligned & =0.02 & p=K_ H (Henry law) & 2=K_ H 0.02...(i) aligned Pressure doubled. aligned & p=K_ H & 4=K_ H ...(ii) aligned From Eqs. (i) and (ii) 1 2 = 0.02 =0.04
