A. They increase the rate at which a reaction reaches dynamic equilibrium.
B. They decrease the concentration of the product.
C. They act as buffers.
D. They decrease the concentration of an intermediate reaction.

Yes. All catalysts do is increase the rate of reaction.

Thank you.

yeah it will increase the rate. But remember they don't increase the yield neither do they change the enthalpy of a reaction.
