A certain catalyst undergoes sintering over time, causing its catalytic activity to decrease according to the following deactivation kinetic model: da kaa² dt The deactivation constant (ka, day¬!) follows an Arrhenius-type temperature-dependency as shown: -1,200 ka = 88.9e nen its activity falls to 98% below its original activity, the catalyst is to be replaced. How long buld this catalyst be used if the reactor is operated at T = 600 K?

A certain catalyst undergoes sintering over time, causing its catalytic activity to decrease according to the following deactivation kinetic model: da kaa? dt The deactivation constant (ka, day-!) follows an Arrhenius-type temperature-dependency as shown: -1,200 ka = 88.9e When its activity falls to 98% below its original activity, the catalyst is to be replaced. How long should this catalyst be used if the reactor is operated at T = 600 K?
