Respuesta :
The addition of gas C to the mixture at constant pressure, reduces the mole fraction of gas A.
Partial pressure is given as the pressure exerted by the individual molecules in a mixture. The partial pressure of a gas in a mixture is given as:
[tex]\rm Partial\;pressure=\;mole\;fraction\;\times\;total\;pressure[/tex]
Effect of gas C on mole fraction of gas A
The total pressure of the mixture is the sum of the partial pressure of individual gas. If the addition of one gas result s in no change in the total pressure, then the factors governing the partial pressure are changed.
Since, the addition of C has constant total pressure, the mole fraction of gas A in the mixture is decreased in order to keep constant total pressure.
Thus, the addition of gas C to the mixture at constant pressure, reduces the mole fraction of gas A.
