Question

Which of the following is not true about a catalyst?

• A. A catalyst causes a reaction to proceed at a faster rate.
• B. A catalyst lowers the activation energy of a reaction.
• C. A catalyst affects the rate of both the forward and the reverse reaction.
• D. A catalyst increases the rate constant of a reaction.
• E. A catalyst increases the equilibrium constant of a reaction.

Answer 1

The correct option is E A catalyst increases the equilibrium constant of a reaction.

A catalyst does increases the equilibrium constant of a reaction.
Thus, a catalyst does not affect the position of equilibrium.
