MHT CET 2025 Chemistry question

If = -0.76 V. Calculate potential for at 298 K?

(A)+0.8192 VCorrect
(B)-0.8192
(C)+0.7008 V
(D)-0.7008 V

Answer: (A)

Solution

The given V is for the reduction . For the oxidation half-reaction the standard potential has the opposite sign: V. Nernst equation for the oxidation: $ = -
