(PDF) ESSENTIAL CELL BIOLOGY ESSENTIAL CELL ... - Academia.edu Academia.edu is a platform for academics to share research papers. Gibbs free energy - Wikipedia The reaction will only be allowed if the total entropy change of the universe is zero or positive. This is reflected in a negative ΔG, and the reaction is called an exergonic process. If two chemical reactions are coupled, then an otherwise endergonic reaction (one with positive ΔG) can be made to happen. Gibbs free energy - chemguide ΔG = ΔH - TΔS. Remember that for a reaction to be feasible, ΔG has to be negative. ΔH could be negative (an exothermic reaction) or positive (an endothermic reaction). Similarly ΔS could be either positive or negative. There are four possible combinations of the signs of ΔH and ΔS. I want to look at those in turn.
