Enzymes in plants convert nitrate into ammonia.The unbalanced half-reaction equation is given below.What is the stoichiometric coefficient of the nitrite ion in the balanced reaction equation?
NO₃ -(aq) + H₂O(l) + e^-

\rightarrow

NO₂ + (aq) ++OH^-(aq)

Quizplus · Accepted Answer

The balanced half-reaction for the conversion of nitrate to ammonia involves nitrate (NO3-) being reduced to ammonia (NH3), with nitrite (NO2-) as an intermediate product. The stoichiometric coefficient of nitrite ion in the balanced equation is 1, as it is produced and then consumed in the process.
