Striking of match:
The process is carried out for obtaining the minimum amount of activation energy for starting or initiating the chemical reaction, which is obviously getting fire to use.
Explanation:
Optimum amount of energy:
For any reaction or process to start there is an optimum amount of energy that is required for initiating or starting of any process. Such, is also in the case of striking the match.
