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 Total Pressure for Binary Vapour System for Dew-Bubble Point calculations with Modified Raoult's Law?
Total Pressure for Binary Vapour System for Dew-Bubble Point calculations with Modified Raoult's Law calculator uses Total Pressure of Gas = 1/((Mole Fraction of Component 1 in Vapour Phase/(Activity Coefficient of Component 1*Saturated Pressure of Component 1))+(Mole Fraction of Component 2 in Vapour Phase/(Activity Coefficient of Component 2*Saturated Pressure of Component 2))) to calculate the Total Pressure of Gas, The Total Pressure for Binary Vapour System for Dew-Bubble Point calculations with Modified Raoult's Law formula is defined as the reciprocal of the summation of the ratio of mole fraction of i th component to the product of activity coefficient of i th component and the saturated pressure of i th component, where i = 2 for the binary system. Total Pressure of Gas is denoted by PT symbol.
