WebSep 14, 2015 · 0. Delta G naught means that the reaction is under standard conditions (25 celsius, 1 M concentraion of all reactants, and 1 atm pressure). Delta G naught prime means that the pH is 7 (physiologic conditions) everything else is the same. The concentration of [H+] now isn't 1 molar because 1 molar concentration would be an extremely low pH (0). WebQ is our reaction quotient; It tells us where we are in the reaction, and remember, it has the same form as the equilibrium constant K. Delta G zero is the standard change in free energy, so the change in free energy …

When the products are more stable than the reactants, Δ Gorxn is negative, and the reaction is exergonic. If the reactants less stable than the products, Δ Gorxn is positive, and the reaction is endergonic.
