Solution
Para resolver este problema, primero necesitamos determinar la cantidad de dinitrógeno (N₂) que se consume por segundo en moles, y luego usar la estequiometría de la reacción de Haber para encontrar la cantidad de amoníaco (NH₃) producido. Finalmente, convertiremos esa cantidad a kilogramos por segundo.
-
Determinar los moles de N₂ consumidos por segundo:
Usamos la ecuación de estado de los gases ideales:
Donde:
- es la presión (0.64 atm)
- es el volumen (349 L/s)
- es el número de moles
- es la constante de los gases ideales (0.0821 L·atm/(K·mol))
- es la temperatura en Kelvin (222°C + 273.15 = 495.15 K)
Reorganizamos la ecuación para resolver :
Sustituimos los valores:
Calculamos:
-
Usar la estequiometría de la reacción de Haber:
La reacción de Haber es:
Según la estequiometría, 1 mol de N₂ produce 2 moles de NH₃. Por lo tanto, 5.50 mol de N₂ producirán:
-
Convertir moles de NH₃ a kilogramos:
La masa molar del NH₃ es:
Convertimos moles a gramos:
Convertimos gramos a kilogramos:
Redondeamos a dos cifras significativas:
Por lo tanto, la tasa a la que se produce amoníaco es aproximadamente 0.19 kilogramos por segundo.
