Question

The rate of a reaction or how quickly a reaction will proceed is best determined by?

Answer 1

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
