Question

During the combustion of NH3, there is an increase in the amount of oxygen present, from 5 to 20 moles while the amount of NH3 remains unchanged. Given this change in oxygen, what can we say about this chemical reaction?

Answer 1

Answer: The ratio of NH3 to NO produced will remain constant

Explanation: The ratio of NH3 to NO produced will remain constant since NH3 is the limiting reactant. No matter how much oxygen is added to the reaction, without additional NH3, no additional NO will be produced.

Answer 2

Step-by-step 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.
