The chemical potential of a pure substance depends upon the temperature and pressure

The chemical potential of a component in a system is directly proportional to the escaping tendency of that component

_{i}) in an ideal gas mixture approaches zero as the pressure or mole fraction (x_{i}) tends to be zero at constant temperature

_{i}) is mathematically represented as,μ_{i} = ∂(nG)/∂ni]_{T,P,nj} where, n, n_{i} and n_{j} respectively denote the total number of moles, moles of i^{th} species and all mole numbers except ith species. 'G' is Gibbs molar free energy

Activity co-efficient is dimensionless.

In case of an ideal gas, the fugacity is equal to its pressure.

In a mixture of ideal gases, the fugacity of a component is equal to the partial pressure of the component.
