Solution

The correct option is D Assertion is incorrect but Reason is correct
In $[F e (C N)_{6}]^{4 -} \to F e^{3 +} + C O_{2} + N O_{3}^{-}$
Change in oxidation state of Fe $= 3 - 2 = 1$
Change in oxidation state of C $= 4 - 2 = 2$
Change in oxidation state of N $= 5 - (- 3) = 8$
So, equivalent weight of $[F e (C N)_{6}]^{4 -} = \frac{M o l . w t .}{1 + 6 \times (2 + 8)} = \frac{M o l . w t .}{61}$
