NEET Solved Paper 2017 Question 22
Question: Which one of the following statements is not correct?
Options:
A) Coenzymes increase the catalytic activity of enzyme
B) Catalyst does not initiate any reaction
C) The value of constant is changed in the presence of a catalyst in the reaction at equilibrium
D) Enzymes catalyse mainly bio-chemical reactions
Show Answer
Answer:
Correct Answer: C
Solution:
- 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.
