For a thermokinetic oscillator, the reaction scheme is , . The second reaction is exothermic with a reaction enthalpy ; it has a substantial activation energy . The concentration of component is constant, the temperature of the surroundings is , the density and specific heat of the reaction mixture are and , the area for heat transfer is , the volume of the system is , , , and . The relevant rate equations are solved and plotted for and , the latter scaled up by 1000 for convenience.
The reaction produces heat, accelerating the reaction and reducing the concentration of . As you vary the parameters, the interplay of these opposing tendencies can produce oscillations and bifurcation behavior.
