Se lleva a cabo una reaccin irreversible de primer orden sobre un catalizador de dimensin caracterstica 0,2 cm y difusividad efectiva de 0,015 cm 2 /s. A 100 o C, se ha medido que la constante de velocidad intrnseca es de 0,93 s -1 con una energa de activacin de 20 kcal/mol.

a. Para una concentracin superficial de 3.25 x10 -2 mol/L, cul es la velocidad de reaccin observada a 100 o C?

b. Para la misma concentracin de reactivo, cul es la velocidad de reaccin observada a 150 o C? Suponiendo que la difusividad es independiente de la temperatura.

C. Qu valor de la energa de activacin se observara?

d. Compare los valores del mdulo de Thiele a 100 o C y 150 o C.
