6. (15%) An experimental rate measurement on the decomposition of A is made with a particular catalyst. For the spherical particle: d_p = 2.4 mm, D_e = 5 x 10^-5 m³/hr-m cat (Effective mass conductivity), k_eff = 1.6 kJ/hr-m cat-K (Effective thermal conductivity), for the gas film surounding the pellet: h = 160 kJ/hr-m² cat-K (heat transfer coefficient), kg = 300 m³/hr-m² cat (mass transfer coefficient), for the reaction: AH, = -160 kJ/mol A (exothermic), C_Ag = 20 mol/m³ (at 1 atm, 336 ℃), -r"_A,obs = 10⁵ mol/hr-m³ cat.
