<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
It means that the chemical equation is balanced
