The dissolution of aspirin tablet is controlled by the diffusion of the drug into the surrounding stomach fluid. The table has a radius R. The drug concentration at the surface is always saturated, ie, C(r=R)=C0. What is the drug concentration profile outside the tablet in the stomach fluid? State all your assumptions and boundary conditions in your calculation.
