An analysis is presented for a gas-solid heterogeneous, noncatalytic reaction which propagates from the center. The results are compared with those for a shrinking-core model. The analysis reveals that the reaction rate.can exhibit a maximum or a discontinuity. For a first-order reaction, the moving reaction interface is always stable toward a one-dimensional perturbation. © 1987, American Chemical Society. All rights reserved.
