Which of the following statements is incorrect?
- The equilibrium constant of a reaction changes when a catalyst is present at equilibrium
- Enzymes mainly catalyse biochemical reactions
- Coenzymes enhance the catalytic activity of enzymes
- A catalyst does not initiate any reaction
Correct answer: The equilibrium constant of a reaction changes when a catalyst is present at equilibrium
Solution
A catalyst speeds up forward and reverse reactions equally and does not change the equilibrium constant Kc. So 'the equilibrium constant changes when a catalyst is present' is the incorrect statement. The other three statements are correct.
