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 Gibbs Free Energy using Ideal Gibbs Free Energy, Pressure and Fugacity?
Gibbs Free Energy using Ideal Gibbs Free Energy, Pressure and Fugacity calculator uses Gibbs Free Energy = Ideal Gas Gibbs Free Energy+[R]*Temperature*ln(Fugacity/Pressure) to calculate the Gibbs Free Energy, The Gibbs Free Energy using Ideal Gibbs Free Energy, Pressure and Fugacity formula is defined as the sum of ideal Gibbs free energy and the product of the universal gas constant, temperature and the natural logarithm of the ratio of the fugacity to the pressure. Gibbs Free Energy is denoted by G symbol.
