The effect of temperature on the spontaneity of reactions are represented as: Which of the following is correct?

All reactants need to overcome certain energy, better known as activation energy in order to form products. This activation energy is the difference between the energy of the transition state and the reactant species.
Catalysis of chemical reactions is generally divided into two categories:
