Temperature coefficient of the fugacity and standard chemical potential

Temperature coefficient of the fugacity and standard chemical potential 

Consider this equation as being applied to conditions of low pressure where the fugacity of the gas i becomes equal to its partial pressure. Then o  

These equations are identities and can be partially differentiated with respect to temperature. Thus 

The final term in the second of these equations is zero. Substituting from (2-113) 

In (3 63) Hi is the partial molar enthalpy in the imperfect mixture t For more complete details see Prausnitz, loc, cU,
