In the reaction when one mole of ammonia and one mole of oxygen are made to reac

In the reaction \( 4 N H_{3}+5 O_{2} \longrightarrow \) \( 4 N O+6 H_{2} O, \) when one mole of ammonia and one mole of oxygen are made to react to completion, then

  • A. 1.0 mole of \( H_{2} O \) is produced
  • B. All the oxygen is consumed
  • C. 1.5 mole of \( N O \) is formed
  • D. All the ammonia is consumed

Step-by-step solution

The balanced equation shows a 4:5 mole ratio of NH₃ to O₂. With 1 mole each, O₂ is limiting because it requires 1.25 moles of O₂ to fully react with 1 mole of NH₃, but only 1 mole is available. Thus, all oxygen is consumed, leaving some ammonia unreacted.
