Consider the following redox reaction taking place in acidic medium
\( BH_{4}^{-}(aq)+ClO_{3}^{-}(aq) → H_{2}BO_{3}^{-}(aq)+Cl^{-}(aq) \).
If the Nernst equation for the above balanced reaction is
\(E _{ cell }= E _{ cell }^{ o }-\frac{ RT }{ nF } \ell n Q\),
Then the value of \(n\) is __________ . (Nearest integer)
- A 6
- B 12
- C 24
- D 8
Answer & Solution
Correct Answer
(C) 24
Step-by-step Solution
Detailed explanation
\( 3BH_{4}^{-}+4ClO_{3}^{-} \rightarrow 4Cl^{-}+3H_{2}BO_{3}^{-}+3H_{2}O \) n -factor \(=8\) moles \(=3\) \(\therefore n =3 \times 8=24\)
