Ideal Solution Entropy using Excess and Actual Solution Entropy Solution

STEP 0: Pre-Calculation Summary

Formula Used

Ideal Solution Entropy = Entropy-Excess Entropy
S^id = S-S^E
This formula uses 3 Variables

Variables Used

Ideal Solution Entropy - (Measured in Joule per Kelvin) - Ideal solution entropy is the entropy in an ideal solution condition.
Entropy - (Measured in Joule per Kelvin) - Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
Excess Entropy - (Measured in Joule per Kelvin) - Excess entropy is the entropy of a solution in excess of what it would be if it were ideal.

STEP 1: Convert Input(s) to Base Unit

Entropy: 16.8 Joule per Kelvin --> 16.8 Joule per Kelvin No Conversion Required
Excess Entropy: 32 Joule per Kelvin --> 32 Joule per Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S^id = S-S^E --> 16.8-32

Evaluating ... ...

What is Excess Property?

Excess properties are properties of mixtures which quantify the non-ideal behavior of real mixtures in chemical thermodynamics. They are defined as the difference between the value of the property in a real mixture and the value that would exist in an ideal solution under the same conditions. The most frequently used excess properties are the excess volume, excess enthalpy, and excess chemical potential. The excess volume, internal energy, and enthalpy are identical to the corresponding mixing properties.

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.
