Solution

The correct option is A Through experimentation.
You determine the reaction order through experimentation.
The order of the reaction is not related to the stoichiometric equation of the reaction. This implies that the order of a reaction cannot be predicted from the stoichiometric balanced equation of the reaction. It is strictly an experimentally determined quantity.
