For an exothermic, gas-phase reaction in a plug flow reactor (PFR) with heat exchange, this Demonstration plots the temperature and molar flow rate of the reactant as a function of distance down the reactor. The feed temperature, the activation energy for the rate constant, and the total molar flow rate can be varied. Thermal runaway is shown to be a sensitive function (parametric sensitivity) of the feed temperature and the activation energy.
