WebEndergonic reaction. An endergonic reaction (such as photosynthesis) is a reaction that requires energy to be driven. Endergonic means "absorbing energy in the form of work." The activation energy for the reaction is typically larger than the overall energy of the exergonic reaction (1). Endergonic reactions are nonspontaneous. WebThe maximum work obtainable from a chemical reaction is equal to delta G.

WebThe first law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes.A simple formulation is: "The total energy in a system remains constant, although it may be converted from one form to another." Another common phrasing is that "energy can neither be created nor destroyed" (in a "closed system"). WebIf Δ H is positive, and – T Δ S negative, the reaction will be spontaneous at high temperatures (increasing the magnitude of the entropy term). Sometimes it can be helpful to determine the temperature when Δ G ⁰ = 0 and the process is at equilibrium.
