Detailed explanation-1: -If the free energy change G for a reaction is-46.11 kJ/mol, the reaction is: D) exergonic. (Remember, -delta G=exergonic due to loss of energy while + delta G=endergonic due to energy being required.)

Detailed explanation-2: -In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). This indicates a spontaneous reaction if the system is closed and initial and final temperatures are the same.

Detailed explanation-3: -Reactions that have a negative ∆G release free energy and are called exergonic reactions. (Handy mnemonic: EXergonic means energy is EXiting the system.) A negative ∆G means that the reactants, or initial state, have more free energy than the products, or final state.

Detailed explanation-4: -Endergonic reactions require an input of energy; the ∆G for that reaction will be a positive value. Exergonic reactions release free energy; the ∆G for that reaction will be a negative value.

Detailed explanation-5: -In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger than the bonds being broken. In an endergonic reaction, energy is absorbed from the surroundings. The bonds being formed are weaker than the bonds being broken.
