Which statement concerning overvoltage is false?

Question

Quizplus · Accepted Answer

Overvoltage is the additional voltage required to initiate a redox reaction at an electrode, and it is often due to a high activation energy. However, some half-reactions involving the formation of gases such as O2 or H2 have a very high overvoltage, while others involving the formation of gases such as Cl2 or Br2 have a much lower overvoltage. Therefore, statement C is false because overvoltage can be significant for some half-reactions even if they involve the formation of gases. Statements A, B, and D are all true.
