Cinética intrínseca cstr

Procedimiento iterativo para calcular la constante cinética intrínseca a partir de la constante cinética aparente

Ajuste de los datos experimentales a un modelo cinético

1. Los datos experimentales obtenidos en por ciento peso se convirtieron a concentración molar, y con ello se obtuvo la conversión correspondiente:
