Variables Used
Activity Coefficient in Raoults Law - Activity Coefficient in Raoults Law is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances.
K value - K value is defined as the ratio of vapor-phase mole fraction to the liquid phase mole fraction.
Total Pressure of Gas - (Measured in Pascal) - Total pressure of Gas is the sum of all the forces that the gas molecules exert on the walls of their container.
Saturated Pressure in Raoults Law - (Measured in Pascal) - Saturated Pressure in Raoults Law is the pressure at which a given liquid and its vapour or a given solid and its vapour can co-exist in equilibrium, at a given temperature.
STEP 1: Convert Input(s) to Base Unit
K value: 0.85 --> No Conversion Required
Total Pressure of Gas: 102100 Pascal --> 102100 Pascal No Conversion Required
Saturated Pressure in Raoults Law: 200 Pascal --> 200 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
γRaoults = (K*PT)/PSaturated --> (0.85*102100)/200
Evaluating ... ...
γRaoults = 433.925

Define K-Value and it's Relation with Relative Volatility (α).

The K value or vapour-liquid distribution ratio of a component is the ratio of vapour mole fraction of that component to the liquid mole fraction of that component. A K value for a more volatile component is larger than a K value for a less volatile component. That means that α (relative volatility) ≥ 1 since the larger K value of the more volatile component is in the numerator and the smaller K of the less volatile component is in the denominator.

What are the Limitations of Henry Law?

Henry law is only applicable when the molecules of the system are in a state of equilibrium. The second limitation is that it does not hold true when gases are placed under extremely high pressure. The third limitation that it is not applicable when the gas and the solution participate in chemical reactions with each other.
