This parody (written by Greg Crowther) is sung to the tune of
Alex Harvey and Larry Collins
and performed by
Delta G -- plus or minus it will be
For reactions in conditions that are known.
If delta H is less than T times delta S,
The reaction can go forward on its own.
The Gibbs free energy gives me satisfaction
From gauging the spontaneity of reactions.
Its equation has an "H" -- that's enthalpy --
And entropy is "S" and temperature's "T."
The equation shows if reactions can proceed,
But it doesn't say a thing about their speed.
The study of those rates is called Kinetics,
And it uses lots more math that'll give you headaches.

This song provides a concise introduction to Gibbs
free energy (ΔG) and the equation by which it is calculated
(ΔG = ΔH - TΔS).
