Answer:
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Reactants are the starting materials, while products are the end result of the reaction. All chemical reactions are accompanied by a change in entropy.
In general, chemical reactions can be classified as either redox reactions or non-redox reactions. In redox reactions, there is a transfer of electrons between reactants. In non-redox reactions, there is no electron transfer. All exothermic reactions are redox reactions, while endothermic reactions may be either redox or non-redox.
