Because entropy and free-energy dissipating irreversible processes generate and maintain these structures, these have been called dissipative structures. The hypothesis of an increase in free energy (exergy) by ecosystems during evolution is tested on direct measurements.
So ΔG is the net energy available to do useful work and is thus a measure of the ‘free energy’. For this reason, it is also known as the free energy of the reaction. ΔG gives a criteria for spontaneity at constant pressure and temperature. (i) If ΔG is negative ( 0), the process is spontaneous. (ii) If ΔG is positive (> 0), the process ...

The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position r. The force you must exert to move it must be equal but oppositely directed, and that is the source of the negative sign. The force exerted by the force field always tends...

The concept of free energy allows prediction of spontaneity of a process by considering the changes in _____ and _____ during the process. A) enthalpy; mass B) entropy; temperature C ) enthalpy; temperature D) enthalpy; entropy E) entropy; mass

We draw on case study interviews to argue that an approach that emphasizes the interplay of energy and entropy in determining spontaneity (one that involves a central role for free energy) is one that draws on students' resources from biology and chemistry in particularly effective ways.

Gibbs free energy and spontaneity How the second law of thermodynamics helps us determine whether a process will be spontaneous, and using changes in Gibbs free energy to predict whether a reaction will be spontaneous in the forward or reverse direction (or whether it is at equilibrium!).
