Give the name of the reaction that achieves the theoretical limits with respect to free energy in thermodynamics. a. reversible reactionb. forward reactionc. irreversible reactiond. equilibrium reaction

The correct option is: a. reversible reaction

Explanation:

In thermodynamics, Gibb's free energy is the quantitative measure of the spontaneity or feasibility of a chemical reaction, at fixed temperature and pressure.

It can also be described as the maximum available work obtained from a closed system. This maximum work can only be achieved in a reversible process, at fixed pressure and temperature.

The Gibb's free energy (ΔG) is given by: ΔG = ΔH - T.ΔS
