Derive the concentration profile as a function of radial distance from the dissolving sphere and its variation over time. assume one-dimensional diffusion of species a in a binary mixture occurs from the spherical particle is radially outward and assume quasi- steady process. assume newtonian fluid if it , assume all the physical properties are known including solubility (c) and ignore the temperature dependence of the physical properties of the polymers and the oil.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
