Answer:
C. is less than 0
Explanation:
The Gibbs free energy (G) of a system is defined as the energy that is used for the work done. The change in Gibbs free energy during a reaction shows the spontaneity and energetics of the reactions.
A reaction will be spontaneous if the change in Gibbs free energy will be negative or less than 0. Reactions with positive Gibbs free energy are non-spontaneous.
Hence, the correct answer is "C. is less than 0".
