Webb1 dec. 2007 · The standard Gibbs free energy of formation of MoO2 d, DfG (MoO2 d), has been measured over a wide temperature range (925 to 1925) K using an advanced version of bi-electrolyte solid-state... The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, in their standard states (the most stable form of the element at 25 °C and 100 kPa). Its symbol is ΔfG˚. All elements in their standard states (diatomic oxygen gas, graphite, etc.) have standard Gibbs free energy change of formation equal to zero, as there is no change involved.

WebbThe standard reaction Gibbs energies (at pH=7) for the hydrolysis of glucose-1-phosphate, glucose-6-phosphate, and glucose-3-phosphate are -12, -14, -9.2 kj/mol, respectively. Calculate the equilibrium constants for the hydrolyses at 37C. 4.14 The standard Gibbs energy for the hydrolysis of ATP to ADP is -31kj/mol. WebbThe standard Gibbs free energy of formation of an element in its standard state is 0 ΔG ƒ ° (element) = 0 Values of standard Gibbs free energy of formation can be used to calculate the change in Gibbs free energy for a chemical reaction or physical change: reactants → products ΔG° (reaction) = ΣG ƒ ° (products) − ΣG ƒ ° (reactants) WebbThe standard Gibbs energy of formation for H2O (g) is AG.H200--228.57kJmol.
