Question

вычислите выход продукта реакции каталитического окисления аммиака на промышленной установке,если при окислении порции аммиака массой 102 кг в среднем получается монооксид азота массой 117 кг

Answer 1

Уравнение:
4NH3 + 5O2 = 4NO + 6H2O

Рассчитем количество вещества аммиака:
n = m/M = 102000г/17г/моль = 6000 моль = 6кмоль

По уравнению реакции:
n(NO0 = n(NH3) = 6 кмоль

Рассчитем массу 6 кмоль монооксида:
m = n*M =  6кмоль*30кг/кмоль = 180 кг

Рассчитаем выход продукта:
q = m(практ)/m(теор)*100% = 117кг/180кг*100% = 65%

 

 

Answer 2

Calculating the Output of the Reaction

To calculate the output of the reaction of catalytic oxidation of ammonia on an industrial installation, we can use the given information that when 102 kg of ammonia is oxidized, the average yield is 117 kg of nitrogen monoxide (NO).

The balanced chemical equation for the catalytic oxidation of ammonia is: 4NH3 + 5O2 → 4NO + 6H2O

Using this equation, we can calculate the theoretical yield of nitrogen monoxide (NO) when 102 kg of ammonia is oxidized.

First, we need to find the molar mass of NH3 and NO: - Molar mass of NH3 (ammonia) = 17.03 g/mol - Molar mass of NO (nitrogen monoxide) = 30.01 g/mol

Now, we can calculate the theoretical yield of NO: - Convert the mass of ammonia to moles: - Moles of NH3 = Mass of NH3 / Molar mass of NH3 - Use the mole ratio from the balanced chemical equation to find moles of NO produced: - Moles of NO = Moles of NH3 * (4 moles of NO / 4 moles of NH3)

Finally, convert the moles of NO to kilograms: - Mass of NO = Moles of NO * Molar mass of NO

Let's calculate the theoretical yield of NO using the given information.

Calculation

- Molar mass of NH3 (ammonia) = 17.03 g/mol - Molar mass of NO (nitrogen monoxide) = 30.01 g/mol

Moles of NH3 = 102,000 g / 17.03 g/mol = 5989.44 mol Moles of NO = 5989.44 mol * (4 mol NO / 4 mol NH3) = 5989.44 mol

Mass of NO = 5989.44 mol * 30.01 g/mol = 179717.94 g = 179.72 kg

Answer

The theoretical yield of nitrogen monoxide (NO) when 102 kg of ammonia is oxidized is approximately 179.72 kg.
