Question 29

Rates of Reaction

Which property of a reversible reaction is affected by a catalyst?

  1. A.Heat content (enthalpy).
  2. B.Energy of activation
  3. C.Free energy change
  4. D.Equilibrium position
Show the answer and explanation

Answer: B (Energy of activation)

Explanation

A catalyst provides a pathway with lower activation energy. It does not change ΔH, the free energy change or the equilibrium position.
