how to differentiate b/w reversible and irreversible reactions without being given the equation symbols

Open in App

Solution

Reversible reaction is that ,in which the reactants react together under certain conditions and form the products and in the same condition the products also recat to form the reactants where as;
Irreversible Reaction is that in which the product once formed can not generate the reactants under same conditions.
