A catalyst is said to be a negative catalyst, if it ___________________?
Correct answer: A. Retards the rate of reaction
- A. Retards the rate of reaction
- B. Reduces the value of equilibrium constant
- C. Does not initiate the reaction
- D. All A., B. and C.
Explanation
A negative catalyst, or inhibitor, lowers the reaction rate by increasing the effective resistance to reaction. It does not change the equilibrium constant, since catalysts affect forward and reverse rates similarly.
