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