Gibbs free energy function from "summary" of Physical Chemistry by Robert G. Mortimer
The Gibbs free energy function is a fundamental concept in thermodynamics that plays a central role in determining the spontaneity of a process. It is defined as the maximum amount of non-expansion work that can be extracted from a thermodynamic system at constant temperature and pressure. This function is denoted by the symbol G and is expressed as the sum of the enthalpy of the system (H) minus the product of the temperature (T) and the entropy of the system (S). The significance of the Gibbs free energy function lies in its ability to predict whether a process will occur spontaneously or not. If the Gibbs free energy change (ΔG) for a process is negative, it means that the process is spontaneous and can occur without the input of external energy. On the other hand, if ΔG is positive, the process is non-spontaneous and will not occ...Similar Posts
