2. Which of the following claims about electrochemical cells is true? a) Cell potential is an extensive property b) Cell potential is an intensive property c) The Gibbs free energy of an electrochemical cell is an intensive property d) Gibbs free energy is undefined for an electrochemical cell
Answer: b Explanation: Because cell potential is independent of the amount of material present, it is an intense attribute. Gibbs free energy is a property that is defined for an electrochemical cell and is a broad characteristic because it is dependent on the amount of material present.
