Question

introduced the concept of fugacity for representing the actual
behaviour of real gas.​

Answer 1

Answer:

NTRODUCTION • The concept of Fugacity was introduced by Gilbert Newton Lewis. ...  For representing the influence of present on Gibbs free energy of real gases by a similar relationship, then the true pressure in the equation should be replaced by an 'effective' pressure, which we call fugacity f of the gas.

Explanation:

Answer 2

Answer:

In chemical thermodynamics, the fugacity of a real gas is an effective partial pressure which replaces the mechanical partial pressure in an accurate computation of the chemical equilibrium constant. It is equal to the pressure of an ideal gas which has the same temperature and molar Gibbs free energy as the real gas.
