(i) `K_(4)Fe(CN)_(6)+3H_(2)SO_(4) rarr 2K_(2)SO_(4)+FeSO_(4)+6HCN`
(ii) `6HCN+12H_(2)O rarr 6HCOOH+6NH_(3)`
(iii) (a) `6NH_(3)+3H_(2)SO_(4) rarr 3(NH_(4))_(2)SO_(4)`
(b) `6HCOOH overset(H_(2)SO_(4))(rarr) 6CO+6H_(2)O`
Above steps of reactions occur in a container starting with one mole of `K_(4)[Fe(CN)_(6)]`, 5 mole of `H_(2)SO_(4)` and enough water. Find out the limiting reagent in step (i) and calculate maximum moles of CO gas and `(NH_(4))_(2) SO_(4)` that can be produced.
