Nat2105 [25]
<h2>Collision Theory </h2>

Explanation:

<h3>The given statement is related to the collision theory - </h3>

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.

<h3>According to the collision theory - </h3>
  • 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
