Question

For a spontaneous change free energy ∆G
Positive
Negative
zero
can be positive or negative​

Answer 1

Answer: Gibbs free energy (G) is a state function defined with regard to system quantities only and may be used to predict the spontaneity of a process. A negative value for ΔG indicates a spontaneous process; a positive ΔG indicates a nonspontaneous process; and a ΔG of zero indicates that the system is at equilibrium
