GENERAL KNOWLEDGE

Detailed explanation-1: -Collision theory states that the rate of a chemical reaction is proportional to the number of collisions between reactant molecules. The more often reactant molecules collide, the more often they react with one another, and the faster the reaction rate.

Detailed explanation-2: -Solution: Collision theory is proposed by Arrhenius. Hence, it is also called as Arrhenius theory.

Detailed explanation-3: -Three things must happen for a reaction to occur. 1) Molecules must collide. 2) Molecules must collide with enough energy to begin to break the old bonds so new bonds can form. ( Remember activation energy) 3) Molecules must collide with the correct orientation.

Detailed explanation-4: -The collision theory is based on the kinetic theory of gases, therefore only dealing with gas-phase chemical reactions are dealt with.
