Question

Which of the following statements is correct?

(a) E°cell and Δ_rG of cell reaction both are extensive properties.

(b) E°cell and Δ_rG of cell reaction both are intensive properties.

(c) E°cell is an intensive property while Δ_rG of cell reaction is an extensive property.

(d) E°cell is an extensive property while Δ_rG of cell reaction is an intensive property.

Answer 1

Correct option (c)

Explanation:

Extensive properties are the properties which depend upon the quantity of the matter contained in the system, e.g., mass, volume, Gibbs free energy, etc. Intensive properties are the properties which depend only upon the nature of the substance and are independent of the amount of the substance present in the system, e.g., heat, boiling point, emf of a cell, etc.
