Question
Models of these chemical systems include the Brusselator and the Oregonator, which were derived from the Lotka–Volterra model used for ecosystems. For 10 points each:
[10m] Name this class of nonlinear autocatalytic reactions that can spontaneously form Turing patterns, such as the chlorite-iodide-malonic acid reaction developed by Lengyel and Epstein and the Belousov–Zhabotinsky reaction.
ANSWER: chemical oscillators [or oscillating reactions; prompt on chemical clocks or clock reactions]
[10h] This chemical oscillator was made by modifying the Belousov–Zhabotinsky reaction by using iodate instead of bromate and additionally using hydrogen peroxide as well as starch as an indicator.
ANSWER: Briggs–Rauscher reaction
[10e] Chemical oscillators are a particularly pronounced example of this type of thermodynamics, in which the system has not reached a steady state.
ANSWER: non-equilibrium [accept equivalents]
