Question

Tymor w Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 445. Iters per second of dioxygen are consumed when the reaction is run at 267. °C and 0.42 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. 0-16

Explanation / Answer

4 NH3 (g)   + 5 O2 (g)    <--------------> 4 NO (g) + 6 H2O (l)

volume = 445 L/s

P V = n R T

n = P V / R T

   = 0.42 x 445 / 0.0821 x 540.15

   = 4.215 mol O2

5 mol O2   ---------------> 4 mol NO

4.215 mol O2   --------------> ??

moles of NO = 4.215 x 4 / 5 = 3.372 mol

mass of NO = 101.2 g

mass of NO formed = 0.10 Kg/s
