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