The results of our preceding work on irreversible (rational) thermodynamics of reacting mixture of fluids and a solid substance are applied to the problem of heterogeneous catalysis. The negative effect of diffusion and the positive effect of surface forces are justified, and the Bronsted-Polanyi equation for the activation energy of surface reaction is obtained.
