Question

A negative DG means that

O the quantity G of energy is available to do work
O the reaction is spontaneous
O the reactants have more free energy than the products
O the reaction is exergonic
O all of the above are true

Answer 1

A negative ΔG indicates that a chemical reaction is spontaneous, exergonic, has reactants with more free energy than the products, and that energy is available to do work.

Step-by-step explanation:

A negative ΔG (delta G) means that the reaction is spontaneous, the reactants have more free energy than the products, the reaction is exergonic, and the quantity G of energy is available to do work. All of the above statements are true.

To clarify, a negative ΔG indicates that the reaction proceeds without additional input of energy and releases free energy; hence, the reaction tends to occur on its own. Exergonic reactions are those where the energy is exiting the system, and reactions with lower free energy in the products compared to the reactants are spontaneous in nature, although they may not occur immediately.
