Question

According to the collision theory, when can a chemical reaction occur?

When enough activation energy is added to correct the orientation of the particle collisions
When reactants collide with enough energy to intersect their valence shells and form new bonds
When reactants collide with enough mass to form new bonds and break apart the reactants
When the proper catalyst is added to break the chemical bonds in the reactants.

Answer 1

when enough activation energy is added to correct the orientation of the particle collisions

Answer 2

According to the collision theory, a chemical reaction occur when enough activation energy is added to correct the orientation of the particle collisions.

What is collision theory?

Collision theory is a hypothesis theory, according to which for the formation of product or for the completion of reaction, reactants molecules should collide with each other with proper orientation.

So, for the collision between the reactant molecules some minimum amount of energy is required which is known as activation energy, to covert into the products.

Hence, option (1) is correct i.e. when enough activation energy is added to correct the orientation of the particle collisions.
