Lets see first what exactly is a Chemical Reaction :-
Lets put slight stress on our mind. Go back to your childhood days. Every one has read about chemical and physical changes. So whenever a chemical change happens, chemical reaction has taken place.
We learnt about the conversion of milk into curd. Burning of paper in air. Basically, the properties of milk has been changed. It can't be regained. Similar happens in burning of paper. Carbon in paper reacts with oxygen in air to form carbon dioxide and leaving behind the ash.
What more we can say about this chemical change ?
THINK
In chemistry we express this change on the basis of Bond Breaking and Bond Formation phenomena.
Reactant/s -----> Product/s
Basically, reactants have undergone changes in the way their atoms were bonded. Atoms have broken their bonds (attractive forces), and rearranged in some another pattern, which is nothing but products.
But, were reactants reactive...or the products stable...???
Well these are the relative terms. Reactants converted into products because their environment was changed. And in that condition (coming in contact with other reactant), the attractive forces of one changed or altered to yield a new species, products.
Looking above, we see that two reactants AB and CD reacted and converted into products AC and BD.
On a broader sense, bonds between AB and CD have been broken and new bonds between AC and BD have been formed.
Many a times it may be the case that from a single reactant products are formed with changing reaction condition(environment).
Everything undergoes changes as per the changing environment...so does the reactants.
Consider the case : AB + CD -----> AC + BD
