Question

In a plant, 1,500 kg of nitrogen oxide is consumed per day to produce 1,500 kg of nitrogen dioxide per day. What is the percent yield? Use mc026-2.jpg.

Answer 1

D. 65.2%

Step-by-step explanation:

Right on edge.

Answer 2

The chemical reaction most likely would be:

NO + 1/2O2 = NO2

We use the chemical reaction and the amount of the reactant to calculate for the theoretical yield. And with the actual yield, we can calculate for the percent yield as follows:

1500 kg NO ( 1 kmol / 38.99 kg ) ( 1 kmol NO2 / 1 kmol NO ) ( 54.99 kg / 1 mol ) = 2119.54 kg NO2

Pecent yield = 1500 kg / 2119.54 kg x100 = 70.90%
