| dc.description.abstract | The present work reports the kinetic modeling of self-hydrolysis of non-buffered, nonstabilized NaBH4 solutions by model-based isoconversional method. The overall kinetics is described by a ‘reaction-order’ model in a practical operating window of 10-20 wt% NaBH4 solutions at 25-80 ºC and 0-50% conversions. The apparent activation energy and preexponential factor are interrelated through a kinetic compensation effect (KCE). The apparent reaction order remains constant at a given temperature irrespective of extent of conversion and decreases with increase in temperature. It decreases from first-order to 0.26 with increase in temperature from 25 to 80 ºC. | por |
