Q3) Pulverized coal pellets, which may be approximated as carbon spheres of radius R = 1.5 mm, are burned in a pure oxygen atmosphere at 1400K and 1.2 atm. Oxygen is transferred to the particle surface by diffusion, where it is consumed in the reaction, C(s) + O2(g) → CO2(g). The reaction rate is first order and of the form R = -k.Co2 at r = R where k = 0.12 m/s. This is the reaction rate per unit surface area of the carbon pellets. Neglecting change in R, determine the steady-state O2 molar consumption rate in mol/s. At 1400K, the binary diffusion coeffici for O2 and CO2 is 1.6x104 m2/s.
