Which of the following might make an irreversible reaction reversible?
A) removing a catalyst
B) increasing the temperature
C) increasing the concentration of the reactants
D) all of the above
Catalyst just alter the rate of reaction.
Exothermic reactions on increasing temperature may become reversible. This is according to LeChateliers principles.
Increasing concentration makes reaction move forward.
So answer is B.
