Question
A chemical reaction is catalyzed by a catalyst $$X.$$ Hence $$X$$
A.
reduces enthalpy of the reaction
B.
decreases rate constant of the reaction
C.
increases activation energy of the reaction
D.
does not affect equilibrium constant of the reaction
Answer :
does not affect equilibrium constant of the reaction
Solution :
A catalyst affects equally both forward and backward reactions, therefore it does not affect equilibrium constant of reaction.
