In redox reaction,

{H}_2 {O}_2

oxidises

{K}_4\left[{Fe}({CN})_6\right]

into

{K}^{+}, {Fe}^{+3}, {CO}_3{ }^{-2}

and

{NO}_3^-

ions in acidic medium, than how many moles of

{H}_2 {O}_2

will react with 1mole of

{K}_4\left[{Fe}({CN})_6\right]

View answer and explanation

Correct option: D

30.5 moles

Option D is correct because the n-factor of H2O2 is 2 and the n-factor of K4[Fe(CN)6] is 61. Therefore, 30.5 moles of H2O2 will react with 1 mole of K4[Fe(CN)6].
