Which one is the assumption of collision theory of reaction rate?
Correct answer: D. All statements are correct
- A. During a chemical reaction the particles must collide
- B. Reaction between the colliding particles can only take place if upon collision they possess the activation energy
- C. Only those collisions are effective which take place in proper orientation
- D. All statements are correct
Explanation
All the given statements are correct (during a chemical reaction the particles must collide, reaction between the colliding particles can only take place if upon collision they possess the activation energy and only those collisions are effective which take place in proper orientation.

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.
