If there is a chemical reaction A→2B on a SPHERICAL (you should take a spherical system) catalytic surface with the boundary conditions given below: BC1 r=0 XA=XA0 ( Xa is the composition of the component A) BC2 r=6 NA=ko (k, is the rate constant of zeroth order chemical reaction and ô is the thickness of diffusion layer) A) Derive the steady state composition of A as a function of r. B) Derive mass transfer rate for component A and determine the steady state flux for A at r=6/2.
