Considering the potential energy surface (PES) of a chemical reaction, how can one predict the transition state structure and the activation energy barriers for a complex multi-step reaction mechanism?

The three conditions of collision theory are: 1 - The particles must:    Collide 2 - The particles must have enough: Energy 3 - The particles must be properly:  ?

Question: What is the fundamental difference between kinetic stability and thermodynamic stability in chemical reactions, and how do they influence reaction rates?

Knowledge about the speed of chemical reactions is extremely important for industrial production, especially when optimizing a process. In this sense, strategies can be developed based on changes in the surface area, concentration of reactants, system temperature, and the use of catalysts. Considering this information, analyze the following statements: I. The frequency and orientation of collisions between the reacting species, as well as the amount of energy in the system, are determining factors for the formation of the activated complex. II. The use of catalysts provides an alternative pathway for the formation of the activated complex with lower activation energy, consequently increasing the reaction rate. III. Exothermic transformations are more advantageous because they release energy during product formation, thereby eliminating the need to supply energy to the reactants. Is it correct to assert that:
