CHEMICAL PROCESSES AND REVERSE REACTIONS
TYPES OF REACTIONS

A chemical reaction is a process in which the reactants undergo changes and produce substances, called products, which are different from them.

Chemical reactions are classified as irreversible and reversible reactions.

Irreversible Reactions

Irreversible reactions occur in one direction only and go on to completion. For example,

  1. When unreactive products are formed
  2. All precipitate reactions are irreversible
  3. Neutralization reaction
  4. Redox reactions
  5. Combustion ...
