Pressure given Gibbs Free Entropy Solution

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

FIRST Step Consider the formula

P = \frac{((S - Ξ) \cdot T) - U}{V T}

Next Step Substitute values of Variables

∴

P = \frac{((71J/K - 70.2J/K) \cdot 298K) - 233.36J}{63L}

Next Step Convert Units

∴

P = \frac{((71J/K - 70.2J/K) \cdot 298K) - 233.36J}{0.063m³}

Next Step Prepare to Evaluate

∴

P = \frac{((71 - 70.2) \cdot 298) - 233.36}{0.063}

Next Step Evaluate

∴

P = 79.9999999999863Pa

LAST Step Rounding Answer

∴

P = 80Pa
