Oscillating chemical reaction

  1. Jun 30, 2009 #1
    I'm interested in oscillating chemical reaction, as Belousov-Zhabotinsky one.
    Does it oscillate "forever" or it relax to a macroscopical stationary state?

    Not forever. Oscillations are a side effect of the compilcated mechanism of otherwise simple reaction - as long as there are reactants present reaction proceeds, at some point there is no more reactants - and it stops.

    So from the differential equations point of view: the attractor set of the system is not really a limit cycle but a fixed point that corrispond at the equilibrium state.

    Limite cycle arises when i consider an infinity of reactants, does it sound right?

    You are probably right, I am not used to this nomenclature.
