Question

Consider the following redox reaction taking place in acidic medium:

${BH}_{4}^{-} (aq) + {ClO}_{3}^{-} (aq) \to H_{2} {BO}_{3}^{-} (aq) + {Cl}^{-} (aq)$

If the Nernst equation for the above balanced reaction is

$E_{cell} = E_{cell}^{\circ} - \frac{R T}{n F} \ln Q,$

then the value of n is_____________. (Nearest integer) [2026]

$3 {BH}_{4}^{-} + 4 {ClO}_{3}^{-} \to 4 {Cl}^{-} + 3 H_{2} {BO}_{3}^{-} + 3 H_{2} O$

$n-factor = 8$

$moles = 3$

$∴$ $n = 3 \times 8 = 24$
