Chemistry Question on Chemical Kinetics
A catalyst is a substance which
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
Answer
shortens the time to reach equilibrium
Explanation
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.
