Question

what does free energy change signify?

Answer 1

Gibbs free energy, enthalpy, and entropy. ... Enthalpy in biology refers toenergy stored in bonds, and thechange in enthalpy is the difference in bond energies between the products and the reactants. A negative ∆H means heat is released in going from reactants to products, while a positive ∆H means heat is absorbed.

Answer 2

Gibbs free energy, enthalpy, and entropy. In a practical and frequently used form of Gibbs free energy change equation, ΔG is calculated from a set values that can be measured by scientists: the enthalpy and entropy changes of a reaction, together with the temperature at which the reaction takes place.And we have Gibbs Free-Energy, the measure of total entropy changes along with the surroundings with constant pressure. Free energy determines whether a chemical reaction is spontaneous or not spontaneous, in the Chemistry 2C course, the main focus is Gibbs Free Energy
