What is the difference between fugacity and fugacity coefficient?
The fugacity coefficient is defined as the ratio fugacity/pressure. For gases at low pressures (where the ideal gas law is a good approximation), fugacity is roughly equal to pressure. Thus, for an ideal gas, the ratio ? = f/P between fugacity f and pressure P (the fugacity coefficient) is equal to 1.What is fugacity and fugacity coefficient for real gas?
The fugacity coefficient is 97.03 atm100 atm = 0.9703. The contribution of nonideality to the molar Gibbs energy of a real gas is equal to RT ln ?.What is the significance of fugacity and fugacity coefficient?
The fugacity coefficient takes a value of unity when the substance behaves like an ideal gas. Therefore, the fugacity coefficient is also regarded as a measure of non-ideality; the closer the value of the fugacity coefficient is to unity, the closer we are to the ideal state.- In the special case of an ideal gas, fugacity equals the system pressure, meaning that the fugacity coefficient equals unity [2]. Activity coefficient of a species in a solution represents the relation between the real fugacity and the fugacity corresponding to an ideal solution (calculated via Lewis-Randall rule).
