WebA reaction where the the free energy of a thermodynamically favorable transformation, such as the hydrolysis of ATP, and a thermodynamically unfavorable one, are mechanistically joined into a new reaction (or may be envisaged to be so joined) is known as a coupled reaction.. To put it another way, two or more reactions may be combined … WebBiochemical free energies are usually given as standard free energies of hydrolysis. For example, the hydrolysis of glucose‐6‐phosphate: The other half of the phosphorylation …

WebIf you add the two equations and apply Hess's Law: CaCO 3 (s) + C (s) + O 2 CaO (s) + 2CO 2 (g) D Gº = -263.96 kJ. You see that the overall equation is product-favored. This is an example of coupling : a reactant-favored reaction is linked to a product-favored reaction so that both reactions yield products. WebFor a thermally averaged rate it is proper to associate the average energy gap with the standard free energy of reaction, HA − HD − λ = ΔG0. Therefore, this expression is equivalent to the classical Marcus’ result for the electron transfer rate. kET = Aexp[− (ΔGo + λ)2 4λkT] where the pre-exponential is.
