Explanation:
The ratio of NH3 to NO produced will remain constant since NH3 is the limiting reactant.
Here in this reaction for every 4 moles of ammonia and 5 moles of oxygen gas , 4 moles of NO and 6 moles of water are formed.
So when the amount of oxygen gas is increased to 20 moles without changing the amount of ammonia , the amount of NO formed does not increase as ammonia becomes the limiting reactant.
The shape of an ammonia molecule is trigonal pyramidal (see the image below).
The N atom is at the top of the pyramid and the three H atoms are at the corners of a triangular base.
