Which is a characterstic of catalyst used in a chemical reaction?

Options

  1. ADecreases rate constant of the reaction
  2. BIncreases activation energy of the reaction
  3. CReduces enthalpy of the reaction
  4. DDoes not affect equilibrium constant of reaction

Correct answer

D. Does not affect equilibrium constant of reaction

Step-by-step solution

Catalyst does not affect equilibrium constant but it alters the path of chemical reaction, hence it alters enthalpy of the reaction, rate constant of the reaction and energy activation.
