Answer:
Gibbs Free Energy (ΔG)
Explanation:
Gibbs Free Energy (G) - Is the energy associated with a chemical reaction that can be used to do useful work. The free energy of a system is the sum of its enthalpy (H) minus the product of the temperature (Kelvin) and the entropy (S) of the system:
G = H -TS--------------------------------------------------------- (1)
ΔG = ΔH - TΔS----------------------------------------------(2)
ΔG = Negative, means the reaction is spontaneous
ΔG = Positive, means the reaction is slow
ΔG = Zero, means the reaction is in equilibrium
