Chemical Kinetics - Result Question 37
37. A catalyst is a substance which
(1983, 1M)
(a) increases the equilibrium concentration of the product
(b) changes the equilibrium constant of the reaction
(c) shortens the time to reach equilibrium
(d) supplies energy to the reaction
Show Answer
Answer:
Correct Answer: 37. (c)
Solution:
- A catalyst increases the rate of reaction but by the same factor to both forward and backward directions. Hence, a catalyst shorten the time required to reach the equilibrium.
