The role of a catalyst in a reversible reaction is to.
A
Increase the rate of forward reaction
B
Decrease the rate of backward reaction
C
Alter the equilibrium constant of the reaction
D
Allow the equilibrium to be achieved quickly
Answer
Allow the equilibrium to be achieved quickly
Explanation
Solution
An increase in rate of reaction in forward direction by a catalyst for a reaction in equilibrium brings in an increase in concentration of products and thus rate of backward reaction also increase to same magnitude and so allow the equilibrium to be achieved quickly.
