Physico Chemical principles involved in the Industrial preparation of NH3 by Haber’s process, H2SO4 by contact process and HNO3 by Ostwald’s process.
Reactions in which the products can be converted back into reactions and vice-versa are known as reversible reactions. Such reactions proceed in forward as well as backward directions and a reversible reaction can be represented by between the reactants and the products.
N2 + 3H2 ⇌ 2NH3
Reactions whose products can’t be converted back into reactants are known as irreversible reactions. Such reactions proceed only in one direction.
NaCl + AgNO3 ⇌ AgCl + NaNO3
