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 Actual Enthalpy using Excess and Ideal Solution Enthalpy?
Actual Enthalpy using Excess and Ideal Solution Enthalpy calculator uses Enthalpy = Excess Enthalpy+Ideal Solution Enthalpy to calculate the Enthalpy, The Actual Enthalpy using Excess and Ideal Solution Enthalpy formula is defined as the sum of excess enthalpy and ideal solution enthalpy. Enthalpy is denoted by H symbol.
