Ideal Solution Entropy using Ideal Solution Model in Binary System Solution

Follow our step by step solution on how to calculate Ideal Solution Entropy using Ideal Solution Model in Binary System?

FIRST Step Consider the formula

S id = (x 1 \cdot S1 id + x 2 \cdot S2 id) - [R] \cdot (x 1 \cdot \ln (x 1) + x 2 \cdot \ln (x 2))

Next Step Substitute values of Variables

∴

S id = (0.4 \cdot 84J/kg*K + 0.6 \cdot 77J/kg*K) - [R] \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Substitute values of Constants

∴

S id = (0.4 \cdot 84J/kg*K + 0.6 \cdot 77J/kg*K) - 8.3145 \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Prepare to Evaluate

∴

S id = (0.4 \cdot 84 + 0.6 \cdot 77) - 8.3145 \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Evaluate

∴

S id = 85.3957303469295J/K

LAST Step Rounding Answer

∴

S id = 85.3957J/K
