Abstract
The fugacity is a term that has Latin origins, referring to pace and speed. Early work somewhere in the 20th century, on fugacity, demonstrated that chemical equilibrium is established by the free energies of reacting material. Since then, various approaches and concepts on fugacity have been provided. The gas fugacity of noble gasses has been studied, and models have been proposed for calculating the solubility of noble gasses. The development of various models has considered pressure effects, differential equilibrium between components and temperature changes. The paper discusses the evolution of various multimedia fugacity models and the fugacity of pure ...
