Question

According to which theory or law is a chemical reaction most likely to occur when two particles with the proper energy and orientation interact with each other

Answer 1

Answer: Collision Theory

Explanation: According to the Collision Theory, the following criteria must be met in order for a chemical reaction to occur:

- Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break.

- Molecules must collide with the proper orientation.

Answer 2

Collision Theory

Explanation:

The given statement is related to the collision theory -

Collision theory was given by William Lewis in 1916.

This theory explains in a qualitative manner that in what way any chemical reaction occurs and the reason for the different reaction rates for different reactions.

According to the collision theory -

• Molecules must collide in order to react
• Sufficient amount of energy is needed for collisions (kinetic energy) so that the chemical bonds should break
• This energy used is known as the activation energy
• On the increase in the temperature, the kinetic energy of the molecule increases and the molecules move faster and collide with a proper orientation at an increased speed
• This increases the rate of a collision that in turn increases the breaking of the bond
