This Demonstration shows the steady-state chemical concentration around and within a spherical chemical reactor that consumes the chemical reaching the sphere via diffusion. The "cross-section view" shows the concentration on a plane through the center of the sphere, with the sphere's surface indicated by the black circle. The "radial view" compares the concentration with that of a fully absorbing sphere of the same size, with the gray region indicating the sphere's interior. The total reaction rate percentage is the rate at which the reactor consumes the chemical relative to the rate for a fully absorbing sphere.
