An Irreversible reaction is one that can not go in both ways. i.e reactants can react to give products but products cant react to give back the reactants. In irreversible reaction, new substances are formed and a huge amount of heat is evolved.
There is reversibility between melting point and freezing point, the differences is if the solid is melting above its melting point, in such case, it is an irreversible reaction.
