WebAs a result, the change in Gibbs free energy = the enthalpy change minus the product of the temperature and entropy changes in the system. If the reaction takes place at a constant temperature {ΔT=0} The Gibbs Helmholtz equation is the name given to this equation. ΔG > 0; the reaction is endergonic as well as non-spontaneous. WebThe water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen : CO + H 2 O ⇌ CO 2 + H 2. The water gas shift reaction was discovered by Italian physicist Felice Fontana in 1780. It was not until much later that the industrial value of this reaction was realized.
