What is Residual Property?
A residual property is defined as the difference between a real gas property and an ideal gas property, both considered at the same pressure, temperature, and composition in thermodynamics. A residual property of a given thermodynamic property (like enthalpy, Molar Volume, Entropy, Heat Capacity, etc) is defined as the difference between that property’s actual (real) value, and that thermodynamic property’s value at those same conditions of temperature, pressure, etc. evaluated for an ideal gas. Basically, the residual property is a measure of how far is a given substance’s deviation from ideality is. It is measuring how far this deviation is.
What is Duhem’s Theorem?
For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
How to Calculate Ideal Gas Enthalpy using Residual and Actual Gas Enthalpy?
Ideal Gas Enthalpy using Residual and Actual Gas Enthalpy calculator uses Ideal Gas Enthalpy = Enthalpy-Residual Enthalpy to calculate the Ideal Gas Enthalpy, The Ideal Gas Enthalpy using Residual and Actual Gas Enthalpy formula is defined as the difference between actual enthalpy and residual enthalpy.
