# What is collision theory of reaction rate?

Collision theory is a theory that governs the rate of reaction and states that there must be collisions before reaction will occur.

There is a need to understand that no reaction will occur until there is collisions between reactant particles and only the effective collisions lead to the formation of products.

## How does collision theory affect reaction rate?

The reaction of reactants in chemical reaction only occurs when particles collide with each other and if there is no reaction then there will be no reaction.

## Collision theory and rates of reaction

So we can boldly say that the rate of reaction is a function of collision theory because when particles do not collide , then there will be no interaction meaning bonds will not be broken and new bonds will not be formed.

Collision rate which deals with the number of frequency of collision of the particles depends on certain factors like temperature, pressure, concentration which can alter the rate of collision and thus rates of reaction.

## Analysis of the collision theory and rates of reaction

lets assume A + B === C

It takes A and B to resect before C will be formed and only happens when particles of A and B interact i.e collide, and it is important to note that if they collide often then rate will increase.

Though it is important for particles to collide before products will be formed but it is also important to mention that not all collisions will form products in chemical reaction.

In fact, it is pertinent tom mention again that no reactions is said to have taken place until there is formation of products.

Reaction rate is not necessarily ascertained by how long the particles have been in the vessel colliding but on the amount of products gotten over time.

## What factors affect collision theory and rates of reaction?

I have to say that any factor that affects collision theory will definitely affect rate of reaction.

I will only talk about 3 factors that can affect collision theory and thus rate of reaction.

## 3 factors that affect collision theory and rates of reaction

There are basically six factors that affect rates of reaction, but I will concentrate on three factors that do affect reaction rate.

In conclusion, collision theory states reaction will not occur until there is collision between the reactant particles and only a fraction of these collisions which is otherwise called the effective collisions leads to the formation of products.

Collision theory and rates of reaction are directly proportional and thus anything that affects collision theory affects reaction rate, so altering factors like Temperature, Concentration and pressure will often affect rates of reaction.
