Question

Which of the following statements is correct regarding Electrochemical cells?

(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

This question was addressed to me in a national level competition.

The query is from Electrochemical Cells in chapter Electrochemistry of Chemistry – Class 12

Answer 1

The correct choice is (b) Cell potential is an intensive property

Explanation: Cell potential is an intensive property as it is independent of the amount of material present. Gibbs free energy is defined for an electrochemical cell and is an extensive property as it depends on the quantity of the material.
