From the above data, the following graph is drawn, and the slope is = -13622

From the above data, the following graph is drawn, and the slope is = -13622

 means fewer or more particles will have the required activation energy.

means fewer or more particles will have the required activation energy.

Therefore, if the reaction goes from higher free energy to lower free energy

Therefore, if the reaction goes from higher free energy to lower free energy
