Here is how the Helmholtz Free Entropy equation looks like.

70.2169 = (71 - (\frac{233.36}{298}))

70.2169J/K = (71J/K - (\frac{233.36J}{298K}))

70.2169 = (71 - (\frac{233.36}{298}))

Helmholtz Free Entropy Solution

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

FIRST Step Consider the formula

Φ = (S - (\frac{U}{T}))

Next Step Substitute values of Variables

∴

Φ = (71J/K - (\frac{233.36J}{298K}))

Next Step Prepare to Evaluate

∴

Φ = (71 - (\frac{233.36}{298}))

Next Step Evaluate

∴

Φ = 70.2169127516779J/K

LAST Step Rounding Answer

∴

Φ = 70.2169J/K
