Abstract

We have calculated the rates of the erosion reaction by the steady-state approximation to confirm its isotope effect at C:H film surfaces observed experimentally. The isotope effect is due to the difference between activation energies of C-H and C-D bond breakings along the reaction coordinate. Calculated results are in good agreement with experimental ones.
