Answer 1

irreversible reactions are changes that happens in a chemical process which once changed from its state we cannot bring it's original state back

Reversible reactions:-
These are reactions which once perfomed , can always be brought back to the reactants' original form of reaction ...
this process can be repeated endless times but the reactants and the products can be obtained from themselves .
it's also called temporary reaction .

example:- Wax ----heat----> Melted wax -----cool----> Wax

Irreversible reaction:-
irreversible Reactions are those which once perfomed ,the reactants can't be obtained back into their original state ,
it's also called as a permanent reaction

example:- Milk ------> CURD
curd cannot be made into Milk again.. hence it's a permanent reaction
