Gibbs Free Entropy Solution

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

FIRST Step Consider the formula

Ξ = S - (\frac{U + (P \cdot V T)}{T})

Next Step Substitute values of Variables

∴

Ξ = 71J/K - (\frac{233.36J + (80Pa \cdot 63L)}{298K})

Next Step Convert Units

∴

Ξ = 71J/K - (\frac{233.36J + (80Pa \cdot 0.063m³)}{298K})

Next Step Prepare to Evaluate

∴

Ξ = 71 - (\frac{233.36 + (80 \cdot 0.063)}{298})

LAST Step Evaluate

∴

Ξ = 70.2J/K
