Enthalpy using Gibbs Free Energy, Temperature and Entropy Solution

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

FIRST Step Consider the formula

H = G + T \cdot S

Next Step Substitute values of Variables

∴

H = 0.2286KJ + 450K \cdot 16.8J/K

Next Step Convert Units

∴

H = 228.61J + 450K \cdot 16.8J/K

Next Step Prepare to Evaluate

∴

H = 228.61 + 450 \cdot 16.8

Next Step Evaluate

∴

H = 7788.61J

Next Step Convert to Output's Unit

∴

H = 7.78861KJ

LAST Step Rounding Answer

∴

H = 7.7886KJ
