Scale in Chemistry
- Homogeneous reactions scale linearly in concentration for simple, single reactions, but many step reactions scale according to a particular mechanism.
- 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.
- 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.
- a) Rates and Arrhenieus equation
- b) Free Energy
- c) Enthalpy
- d) Entropy
