Solution

The correct option is D (b) and (c) above.
Catalyst does not affect the position of equilibrium and hence it does not have any effect on the value of equilibrium constant. only change in temperature can change the equilibrium constant. catalyst only affects the forward and reverse reaction equally.

Q. Assertion :Catalyst changes the equilibrium position. Reason: Catalyst alters the rates of both forward and backward reactions.

Q. A catalyst does not change the position of equilibrium but decreases the rate of backward as well as forward reaction.
