Entropy using Gibbs Free Energy, Enthalpy and Temperature Solution

Follow our step by step solution on how to calculate Entropy using Gibbs Free Energy, Enthalpy and Temperature?

FIRST Step Consider the formula

S = \frac{H - G}{T}

Next Step Substitute values of Variables

∴

S = \frac{1.51KJ - 0.2286KJ}{450K}

Next Step Convert Units

∴

S = \frac{1510J - 228.61J}{450K}

Next Step Prepare to Evaluate

∴

S = \frac{1510 - 228.61}{450}

Next Step Evaluate

∴

S = 2.84753333333333J/K

LAST Step Rounding Answer

∴

S = 2.8475J/K
