  2. Contact process - Wikipedia

    en.wikipedia.org/wiki/Contact_process

    The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5 ) is now preferred.

  3. Contact process (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Contact_process_(mathematics)

    The contact process is a stochastic process used to model population growth on the set of sites of a graph in which occupied sites become vacant at a constant rate, while vacant sites become occupied at a rate proportional to the number of occupied neighboring sites. Therefore, if we denote by the proportionality constant, each site remains ...
