Which is true in case of catalyst? This question has multiple correct options
Which is true in case of catalyst? This question has multiple correct options
- A. A catalyst always initiate a reaction
- B. A catalyst does not alter the position of equilibrium in a reversible reaction
- C. A catalyst remains unchanged in quality and composition at the end of the reaction
- D. Catalysts are sometimes very specific in respect of a reaction
Step-by-step solution
Option A is false because a catalyst speeds up a reaction but does not initiate it. Option C is generally true but not absolute; catalysts can undergo temporary changes, though they are regenerated. Option D is true but less fundamental. Option B is a key principle: a catalyst increases the rates of both forward and reverse reactions equally, leaving the equilibrium constant and position unchanged.
