. In the reaction


4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(9)

when 1 mole of ammonia and 1 mole of O2 are made to react to completion

(a) all the oxygen will be consumed

(b) 1.0 mole of NO will be produced

(c) 1.0 mole of H2O is produced

(d) all the ammonia will be consumed

Best Answer

Correct Option is: (A)

4NH3(g) + 5O2(g) 4NO(g) + 6H2O(t)

             4 moles       5 moles  4 moles  6 moles

⇒1 mole of NH3 requires = 5/4 =1.25 mole of oxygen

while 1 mole of O2 requires = 4/5 = 0.8 mole of NH3.

Therefore, all oxygen will be consumed.
