3.2. Collision theory

Question 1

What can happen if the reaction rate is too high in an industrial process?

Answer 1

possible risk of explosion

Question 2

Before a reaction can take place what does collision theory state?

Answer 2

Particles must collide with

• energy equal to or greater than activation energy
• correct collision geometry
