How many coulombs are required for the reduction.12.55 g of nitrobenzene to aniline in acidic medium. |
|
Answer» Correct Answer - 57900 C The reaction reaction in the acidic medium is : `C_(6)H_(5)NO_(2)+6H^(+)+6e^(-) toC_(6)H_(5)NH_(2)+2H_(2)O` Molar mass of nitrobenzene `(C_(6)H_(5)NO_(2))=6xx12+5xx1+14+2xx16` `=72+5+14+32=123 g mol^(-1)` 123 g of nitrobenzene for reduction require charge `=6xx96500" C"` 12.3 g of nitrobenzene for reduction for reduction require charge `=(6xx(96500" C")xx(12.3 g))/((123 g))=57900" C"` |
