Find the fugacity coefficient of a gaseous species of mole fraction 0.4 and fugacity 25 psia in a mixture at a total pressure of 50 psia

The fugacity coefficient of a gaseous species is 1.25

Explanation:

Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as

Mathematically,

Partial pressure of the gas is expressed as:

Putting this expression is above equation, we get:

where,

= fugacity coefficient of the gas

= fugacity of the gas = 25 psia

= mole fraction of the gas = 0.4

P = total pressure = 50 psia

Putting values in above equation, we get:

Hence, the fugacity coefficient of a gaseous species is 1.25
