The rate of reaction is a measure of how quickly a reactant is used up, or a product is formed.

Collision theory
For a chemical reaction to happen: reactant particles must collide with each other the particles must have enough energy for them to react A collision that produces a reaction is called a successful collision. The activation energy is the minimum

What are the steps of the collision theory ?
1- Two pairs of particles move towards each other . 2- The pairs collide and reform so that each member of the original pair joins with a member of the other pair , forming two new pairs .3- The new pairs are now moving away from each other .

What is the equation for mean time ?
mean time = quantity of product formed / time .

What does gradient mean ?
The gradient of the line is equal to the rate of reaction : the steeper the line , the greater the rate of reaction . and fast reactions finish sooner ( when the line becomes horizontal ) than slow reactions .
