WHAT DOES FUGACITY MEAN IN ENGLISH?
Fugacity
In chemical thermodynamics, the
fugacity of a real gas is an effective pressure which replaces the true mechanical pressure in accurate chemical equilibrium calculations. It is equal to the pressure of an ideal gas which has the same chemical potential as the real gas. For example, nitrogen gas at 0°C and a pressure of has a fugacity of. This means that the chemical potential of real nitrogen at a pressure of 100 atm is less than if nitrogen were an ideal gas; the value of the chemical potential is that which nitrogen as an ideal gas would have at a pressure of 97.03 atm Fugacities are determined experimentally or estimated from various models such as a Van der Waals gas that are closer to reality than an ideal gas. The ideal gas pressure and fugacity are related through the dimensionless
fugacity coefficient. For nitrogen at 100 atm, the fugacity coefficient is 97.03 atm / 100 atm = 0.9703. For an ideal gas, fugacity and pressure are equal so is 1. The contribution of nonideality to the chemical potential of a real gas is equal to RT ln. Again for nitrogen at 100 atm, the chemical potential is μ = μid + RT ln 0.
Definition of fugacity in the English dictionary
The definition of fugacity in the dictionary is Also called: escaping tendency a property of a gas, related to its partial pressure, that expresses its tendency to escape or expand, given by d = dμ/ RT, where μ is the chemical potential, R the gas constant, and T the thermodynamic temperature f. Other definition of fugacity is the state or quality of being fugacious.
