If E^0 ( Al^ +3 _ (aq) Al_ (s) ) = -1.66 V. What is potential of Al_ (s) Al^ +3 (0.1 ,M) + 3 e at 298 K?

MHT CET 2025 Chemistry question

If V. What is potential of at 298 K?

(A)+ 1.540 V
(B)-1.540 V
(C)+1.679 VCorrect
(D)-1.679 V

Answer: (C)

Solution

The given half-reaction is an oxidation, so its standard potential is V. Nernst equation at 298 K: with . $ = 1.66 - (0.1) = 1.66 - 0.0197×(-1) = 1.66 + 0.0197 =
