Entropy given Gibbs Free Entropy Solution

Follow our step by step solution on how to calculate Entropy given Gibbs Free Entropy?

FIRST Step Consider the formula

S = Ξ + (\frac{U + (P \cdot V T)}{T})

Next Step Substitute values of Variables

∴

S = 70.2J/K + (\frac{233.36J + (80Pa \cdot 63L)}{298K})

Next Step Convert Units

∴

S = 70.2J/K + (\frac{233.36J + (80Pa \cdot 0.063m³)}{298K})

Next Step Prepare to Evaluate

∴

S = 70.2 + (\frac{233.36 + (80 \cdot 0.063)}{298})

LAST Step Evaluate

∴

S = 71J/K
