A) Coenzymes increase the catalytic activity of enzyme
B) Catalyst does not initiate any reaction
C) The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium
D) Enzymes catalyse mainly bio-chemical reactions
Correct Answer: C
Solution :
[c] A catalyst decreases activation energies of both the forward and backward reaction by same amount, therefore, it speeds up both forward and backward reaction by same rate. |
Equilibrium constant is therefore not affected by catalyst at a given temperature. |
