     CHEMICAL EQUILIBRIUM

*IRREVERSIBLE  REACTIONS

A reaction which proceeds in a definite direction till its completion is known as irreversible reactions

                        Or

The reaction in which reactants are completely converted into products is known as irreversible reactions

èthis reaction is also known as (one way reaction) (complete reaction) (uni-directional)

EXAMPLE

1)  AgNO₃ + Nacl è AgCl + NaNO₃

2)  C + O₂  è CO₂

REPRESENTATION

It is denoted by single arrow (è)

*REVERSIBLE  REACTIONS

Reactions in which reactants are partially converted into products are known as reversible reactions

                              Or

A reaction in which reactants forms product and after some time products are converted into reactants and an equilibrium is establish is known as reversible reactions

èthis reaction is also known as (incomplete reactions) (two way reaction)(bi-directional)
