Solution
Sure, let's solve this step by step.
-
Write the balanced chemical equation for the oxidation of ammonia:
-
Use the Ideal Gas Law to find the moles of dioxygen consumed per second: The Ideal Gas Law is given by: Where:
- is the pressure (0.27 atm)
- is the volume (876 L)
- is the ideal gas constant (0.0821 L·atm/(K·mol))
- is the temperature in Kelvin (193°C + 273.15 = 466.15 K)
Rearrange the Ideal Gas Law to solve for (moles of dioxygen):
-
Determine the moles of nitrogen monoxide produced per second: From the balanced equation, 5 moles of produce 4 moles of . Therefore, the moles of produced per second is:
-
Convert moles of nitrogen monoxide to mass: The molar mass of is:
Therefore, the mass of produced per second is:
-
Convert grams per second to kilograms per second:
Therefore, the rate at which nitrogen monoxide is being produced is approximately kilograms per second.
