In a gaseous mixture at 20 degree centigrade the partial pressures of the components are hydrogen- 120 torr, CO2- 200 torr, CH4- 320 torr, and C2H4- 105 torr. What are the mole fractions and volume fractions of each component with respect to the mixture?
Dear Student
The partial pressure of :
PH = 120 torr
PCO2 = 200 torr
PCH4 = 320 torr
PC2H4 = 105 torr
Therefore, Total Partial Pressure, PTotal = (120 + 200 + 320 + 105) torr = 745 torr
Thus, Mole Fraction can be estimated -
We know, PH = H . PTotal
where, H is the mole fraction of Hydrogen, H
H = = 0.16
And,
CO2 = = 0.26
CH4 = = 0.429
C2H4 = = 0.14
Though the volume of gas is not provided but for an ideal gas, mole fraction remain equivalent to that of volume fraction.
Therefore, here we can apply the same rule, since we don't have any available data.
