Question

Adding a catalyst to a reaction has an effect similar to
A. increasing volume.
B. increasing pressure.
C. adding water to a reaction.
D. lowering the concentration.

Answer 1

Maybe B)

Adding a catalyst to a reaction has an effect similar to increasing pressure.

Answer 2

Le Chatelier’s principle is an observation about chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.
