87. Solving a chemistry problem

6. How will the rate of the catalytic process and the degree of utilization of the inner surface of the porous catalyst in the form of plates sized 2R0 = 5 mm change if the temperature is lowered from 560 to 500 K? First order reaction with a rate constant, s-1, given by the equation k = 3.5*106exp(-7600/T). The effective diffusion coefficient remains unchanged and equal to 0.7 cm2/s.
