Question

What is the reversible and the irreversible processes?
Any examples?
-No spamming.

Answer 1

The processes that can be reversed are called reversible processes.
Ex Melting, freezing
The processes that can not be reversed are called irreversible processes.
Ex burning

Answer 2

REVERSIBLE PROCESS are those in which we can regenerate reactants from products.......

take for example....
2H2(g) + O2(g) ---> 2H2O(l)
here
when we pass electricity (high voltage) H2O breaks to produce H2+ O2...


but in IRREVERSIBLE PROCESS it is not possible to regenerate reactants from products....
take for example....
C(coal) (s) + O2(g) --> CO2(g)
here once we burn coal we cannot produce it again from CO2 again by any measure/method...

{ in a chemical reaction reactants are those which react to give products.... In 1st equation H2 and O2 are reactants. and H2O is product.......... and in 2nd case C(s) and O2 are reactants and CO2 is product....}



hope it helps.....

have any doubt ? ???mention in comment section...!
