Nitric acid, HNO3, is produced from ammonia and oxygen by the consecutive reactions:

4NH3 + 5O2 => 4NO3 + 6H2O
2NO + O2 => 2NO2
3NO2 + H2O => 2HNO3 + NO
How many grams of nitric acid can be obtained from 1.00kg NH3 if NO in the third reaction is not recycled?
Why is it important that NO in the third reaction is not recycled? Other than that, I know what to do. I just want to know the importance of that last piece of information to the calculations.

Why is it important that NO in the third reaction is not recycled? Well, let me tell you, recycling NO can be a real blast! It would lead to more nitric acid being produced, which might sound like a good idea at first. However, there's a catch! NO is a pollutant and can have harmful effects on the environment. So, by not recycling NO, we can prevent its release into the environment and reduce the negative impact. It's like telling NO to pollution!

The last piece of information, which states that NO in the third reaction is not recycled, is important because it indicates that all the NO produced in the second reaction will be used up in the formation of nitric acid in the third reaction. If NO were to be recycled, it would not be fully consumed in the reaction and would remain in the system, resulting in a lower yield of nitric acid.

By knowing that the NO is not recycled, you can assume that all the NO produced in the second reaction is consumed in the third reaction, enabling you to accurately calculate the maximum amount of nitric acid that can be obtained from 1.00kg of NH3.

The importance of knowing that NO in the third reaction is not recycled is to ensure accurate calculations of the amount of nitric acid that can be obtained from 1.00 kg of NH3.

In the given chemical equation, the third reaction produces nitric acid (HNO3) by reacting nitrogen dioxide (NO2) and water (H2O), with NO (nitric oxide) as a reactant. If NO is not recycled, it means that the entire amount of NO added to the reaction will be consumed in the formation of nitric acid.

If NO were to be recycled, it would mean that some of the NO produced in the reaction would be used again as a reactant in subsequent reactions, leading to a lower overall yield of nitric acid. This recycling process results in a lower percentage of NH3 being converted into HNO3.

By excluding the recycling of NO, we can calculate the maximum amount of nitric acid that can be obtained from 1.00 kg of NH3. This ensures that the calculations are based on the assumption that all the NO added to the reaction is consumed in the formation of nitric acid, thereby maximizing the yield.
