Homework Set # 13: The species equation of continuity Due Date: 12-05-05 Problem #1: (a) A solid sphere of substance A is suspended in a liquid B in which it is slightly soluble, and with which it undergoes a first-order chemical reaction with rate constant . At steady state, the diffusion is exactly balanced by the chemical reaction. Show that the concentration profile is 1 k ′′′ / 0 br R A b A C R e C r e = In which R is the radius of the sphere, C A0 is the molar solubility of A in B (i.e. concentration of A at the sphere surface), and
