Question 3 Experimental reaction rates measured for an irreversible 1st order isothermal reaction using spherical catalyst pellets were as follows: With 8 mm diameter pellets, the reaction rate was 0.12 kmol per kg of catalyst per hour. With 4 mm diameter pellets, the reaction rate was 0.216 kmol per kg of catalyst per hour. Appreciable diffusional limitation was observed in both cases: 1. Determine the intrinsic reaction rate, i.e. the rate at which the reaction would go in the absence of diffusional limitation, and 2. predict what the observed reaction rate would be using 1 mm diameter spherical catalyst pellets.
