HELP GO BACK! - Journey to the Clapeyron-Clausius Equation
Welcome! As you embark on your perilous journey to the Clapeyron-Clausius equation, you must first encounter... Gibbs!
The man himself - Josiah Willard Gibbs. But this man isn't important - the following equation that he derived, however, is very important and is named: The Gibbs free energy equation.
G = H - TS
Don't be afraid; it really isn't that scary. Here we see the Gibbs free energy , G related to the enthalpy , H and the product of the temperature (kelvin) and entropy , TS.
In chemistry, this equation can be useful to classify reactions as SPONTANEOUS or NON-SPONTANEOUS.

However, in a thermodynamic context, this equation is used to derive relations and further equations - as you shall soon see throughout this journey.
