Standard gibbs energy of reaction
WebbGibbs free energy (G) is a state function defined with regard to system quantities only and may be used to predict the spontaneity of a process. ... The standard free energy change for a reaction may also be calculated from standard free energy of formation ΔG°f values of the reactants and products involved in the reaction. WebbThe Van 't Hoff equation relates the change in the equilibrium constant, K eq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, Δ r H ⊖, …

Webbwhere is the Gibbs free energy of reaction under non-standard states at temperature , is the Gibbs free energy for the reaction at , is the extent of reaction, and Qr is the thermodynamic reaction quotient. Since , the temperature dependence of both terms can be described by Van t'Hoff equations as a function of T. WebbThis work focuses on determination of the standard Gibbs energy of reaction Δ R g' 0 of the enolase reaction, the ninth reaction in the glycolysis pathway. Exact Δ R g' 0 values are required to predict the thermodynamic feasibility of single metabolic reactions or even of metabolic reaction sequences under cytosolic conditions.
WebbHowever, available literature standard Gibbs energies of reaction, Δ R g' 0, are calculated using equilibrium-molality ratios K m ', which might lead to a misinterpretation of the glycolytic pathway. It was the aim of this work to thermodynamically investigate the triosephosphate isomerase (TPI) reaction to provide new activity-based reaction data.
