A gas mixture consists of three gases A, B and C with the number of moles 1,2 and 4, respectively.w hich of the gases will have a maximum partial pressure if the total pressure of the mixture is P at a given temperature ?

Text Solution

Verified by Experts

In the mixture, the total number of moles of the constitutent gases`=(1+2+4)=7` mol.
The mole fractions of A, B and C `(1)/(7),(2)/(7) and (4)/(7)`, respectively. Since the mole fraction of C is the highest, its partial pressure will be the highest in the mixture.
