WebThe free energy of a system changes during energy transfers, such as chemical reactions, and this change is referred to as ΔG or Gibbs free energy. The ΔG of a reaction can be negative or positive, depending on whether the reaction releases energy (exergonic) or requires energy input (endergonic). WebView history. In thermodynamics, the chemical potential of a species is the energy that can be absorbed or released due to a change of the particle number of the given species, e.g. in a chemical reaction or phase transition. The chemical potential of a species in a mixture is defined as the rate of change of free energy of a thermodynamic ...

Gibbs Free Energy ΔG = ΔH - TΔS - Chad

Webgibbs free energy change should be always negative. That is not true. $\Delta G$ can be negative. The easiest way is to write the equation with the products as the reactants (most processes are reversible). Now the reaction is not spontaneous, but under the right conditions, (maybe increasing temperature), the products will convert to reactants.
