Answer:
(a) Ideal gas equation for individual gases-
Ideal gas equation for the mixture-
Dividing equation (1) by (2), we have
As we know that molar fraction of a gas is-
From equation (3)&(4), we have
Hence the relation between partial pressure and mole fraction of a gas is-
for 1 mole, i.e.,
n=1
Substituting the value of n in equation (1), we get
Hene Vander Waal's equation for 1 mole of a gas is-
