Gibbs Free Energy using Enthalpy, Temperature and Entropy Solution

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

FIRST Step Consider the formula

G = H - T \cdot S

Next Step Substitute values of Variables

∴

G = 1.51KJ - 450K \cdot 16.8J/K

Next Step Convert Units

∴

G = 1510J - 450K \cdot 16.8J/K

Next Step Prepare to Evaluate

∴

G = 1510 - 450 \cdot 16.8

Next Step Evaluate

∴

G = -6050J

LAST Step Convert to Output's Unit

∴

G = -6.05KJ
