ChemistryMediumassertion reason

Assertion : For three half-cell reactions involving different number of electrons $E_{3} = E_{1} + E_{2}$ .

Reason : When half cell reaction are added, ΔG values can be added accordingly.

Answer:

Solution:

The assertion is false because electrode potentials (E) are intensive properties. Gibbs free energy ( $Δ$ G) is extensive and additive.
