Which one is the assumption of collision theory of reaction rate?
Correct answer: D. All of the above statements are correct.
- A. During a chemical reaction, the particles must collide for a reaction to occur.
- B. Reaction between the colliding particles can only take place if they possess the activation energy upon collision.
- C. Only collisions with the correct spatial orientation are effective in causing a reaction.
- D. All of the above statements are correct.
Explanation
All the given statements are correct assumptions of collision theory.Option A: Acknowledges that collisions are fundamental to initiating chemical reactions.Option B: Highlights the necessity of kinetic energy to overcome the activation energy barrier, allowing the reaction to proceed.Option C: Emphasizes the importance of correct spatial orientation during collisions for effective reactions.Option D: Correctly identifies that all previous options are validated principles of collision theory.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
