When the gas reacts with graphite, temperature is the main influence factor on the reaction speed. Whereas the geometry, permeability, chemical activity, gas pressure, and flow state of the graphite sample are minor influencing factors. 

In the process of gas reaction with graphite, surface compounds must be formed. At the initial stage of the reaction, the following phenomena occurs:

1.Reaction rate varies with concentration of graphite surface compounds

2.The initial reaction rate increases with the opening of pores in graphite products by oxidation. The reaction rate increases with the increase of volume of the opening pores. The opening of pores not only increases the available reaction surface area, but also increases the rate of gas diffusion in graphite products.
