Question

Collision theory states that for a chemical reaction to occur, the reacting particles must collide with one another. The rate of the reaction depends on the frequency of collisions. The theory also tells us that reacting particles often collide without reacting. What 2 things must occur for the collision of the reactants molecules to be successful and the reactant particles react?

Answer 1

1. The collision must have sufficient energy to break the existing bonds and initiate the formation of new bonds.
2. The collision must have the correct orientation for the reacting particles to come into contact in a way that allows the necessary bonds to form.
