A mixture of CH₂Cl₂ (A) and CHCl3 (B) with XA = 0.373 has a total vapor pressure of 0.245 bars at 250 K and the mole fraction of CH₂Cl₂ (A) in the vapor phase is yA = 0.427. Given that the vapor pressure of pure CH₂Cl₂ at 250 K is 0.288 bars, calculate the activity of CH₂Cl₂ in this mixture. Assume that the vapor behaves as an ideal gas.

Question
A
mixture of CH₂Cl₂ (A) and CHCl3 (B) with XA = 0.373 has a total vapor pressure of 0.245 bars at 250 K and the mole fraction of CH₂Cl₂ (A)
in the vapor phase is yд = 0.427. Given that the vapor pressure of pure CH₂Cl₂ at 250 K is 0.288 bars, calculate the activity of CH₂Cl₂ in this
mixture. Assume that the vapor behaves as an ideal gas.
