The expression for the apparent rate constant k(a) of partially diffusion-controlled reactions has been derived in the framework of the percolation approach to the description of the dispersive Gaussian transport of active species in disordered solids. Results obtained lor site- and bond-disordered systems agree with the empirical law k(a) = Bt(-1 + α) and allow to calculate parameters B and α for different types of disorder and for various types of reactions involved in the reaction.
