The following catalytic reaction is conducted in a 0.25 cm spherical pellet. A+ B2 C The reaction follows a Langmuir-Hinshelwood mechanism in which the rate determining step is the surface reaction between an adsorbed molecule of A and an adsorbed atom of B. Based on this, one can derive an overall rate expression for this reaction: kg KC (KC) C# (1+KCA +(K2CB)12 + K_Cc)? The following data is also available. r = Parameter Value Units 90, 100 cm3 mol-1 K2 6,500 cm3 mol-1 K4 64,400 cm3 mol-1 T 523 K DA 0.045 cm2 s-1 CA 5.83 x 10-5 mol cm-3 CB2 1.40 x 10-4 mol cm-3 1.17 x 10-5 mol cm-3 k3 7.41 x 108 g mol-1 cm-3s-1 Cm 1.8 x 10-5 molg-1 Part 1 Determine the concentration of A at the center of the catalyst particle.
