Does Gibbs free energy affect the reaction rate?

The reaction rate is typically affected by concentration, pressure, temperature and surface area.
The Gibbs Free Energy equation consists of two variables, delta H which refers to the enthalpy of a system and delta S which is its' entropy.
The Gibbs Free Energy is important as it tells us if a chemical change is thermodynamically possible.
In order for a reaction to be spontaneous, delta G of the Gibs Free energy must be negative. To achieve that, delta H < 0 and delta S >0.
Therefore, it's the temperature and entropy that affects Gibbs Free Energy indirectly affects the reaction rate as well.
