Scale in Chemistry

  1. Homogeneous reactions scale linearly in concentration for simple, single reactions, but many step reactions scale according to a particular mechanism.
  2. Simple, inhomogeneous reactions scale as length squared; as surface area. example: a Pt catalyst in a hydrogenation reaction. More complicated enzyme reactions may have a complicated scaling.
  3. Belusoz-Zhabotinsky reaction scales in volume related to stirring rate, or effectivness of stirring. This is a mater of diffusion dependence, or mixing, but has a complicated scaling dependent on concentrations.

      Reactions scale with temperature.

    2. b) Free Energy
    3. c) Enthalpy
    4. d) Entropy
