Solution

Claro, vamos a resolver el problema paso a paso.

Primero, necesitamos convertir las masas de los reactivos a moles.

  1. Convertir las masas a moles:

    • Para el metanol (CH₃OH): Masa molar del CH₃OH = 12 (C) + 3 (H) + 16 (O) + 1 (H) = 32 g/mol Moles de CH₃OH = masa / masa molar = 15.0 g / 32 g/mol = 0.46875 moles

    • Para el monóxido de carbono (CO): Masa molar del CO = 12 (C) + 16 (O) = 28 g/mol Moles de CO = masa / masa molar = 10.0 g / 28 g/mol = 0.35714 moles

  2. Determinar el reactivo limitante:

    La reacción balanceada es: CH₃OH (l) + CO (g) → CH₃COOH (l)

    De la ecuación balanceada, vemos que 1 mol de CH₃OH reacciona con 1 mol de CO para producir 1 mol de CH₃COOH.

    • Moles de CH₃OH disponibles: 0.46875 moles
    • Moles de CO disponibles: 0.35714 moles

    El reactivo limitante es el CO porque hay menos moles disponibles en comparación con el CH₃OH.

  3. Calcular el rendimiento teórico de ácido acético (CH₃COOH):

    Dado que el CO es el reactivo limitante, la cantidad de CH₃COOH producida estará basada en los moles de CO disponibles.

    • Moles de CH₃COOH producidos = moles de CO disponibles = 0.35714 moles

    • Masa molar del CH₃COOH = 12 (C) + 3 (H) + 12 (C) + 16 (O) + 16 (O) + 1 (H) = 60 g/mol

    • Masa de CH₃COOH producida = moles × masa molar = 0.35714 moles × 60 g/mol = 21.4284 g

Por lo tanto, el rendimiento teórico de ácido acético (CH₃COOH) es 21.4284 gramos.
