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 Fugacity using Gibbs Free Energy, Ideal Gibbs Free Energy and Pressure?
Fugacity using Gibbs Free Energy, Ideal Gibbs Free Energy and Pressure calculator uses Fugacity = Pressure*exp((Gibbs Free Energy-Ideal Gas Gibbs Free Energy)/([R]*Temperature)) to calculate the Fugacity, The Fugacity using Gibbs Free Energy, Ideal Gibbs Free Energy and Pressure formula is defined as the product of the pressure and the exponential of the ratio of the difference of actual Gibbs free energy by the ideal Gibbs free energy to the product of universal gas constant and temperature. Fugacity is denoted by f symbol.
