Final answer:
A negative delta G indicates a spontaneous reaction in the forward direction, where energy is released and products have less free energy than the reactants.
Step-by-step explanation:
A negative delta G (ΔG) indicates that a chemical reaction is spontaneous in the forward direction. It means that energy is released during the reaction, and the products have less free energy than the reactants. Such reactions are referred to as exergonic and spontaneous reactions. However, it is important to note that a negative delta G does not necessarily mean that the reaction will occur quickly or immediately, as some spontaneous reactions may occur slowly over time.
