this is a quick video over runaway reactions so what we're going to do we're going to graph the the Heat and that could be heat removed or heat generated so we're just going to say this is heat removed or generated so the removal of the heat would be due to the cooling system and the generation of the heat would be due to the reaction and we're going to graph this versus temp temp so as temperature increases for a system the reaction can proceed actually faster so the reaction rate increases so if you increase reaction rate
you increase the heat of the generation of heat so a reaction rate I don't know line would look something like this there comes a point where it just kind of jumps up so this is the generation of heat from a reaction so generation of heat now for a coolant line assuming that you have a constant supply of water just running through at a uniform rate if you increase the temperature of the system you increase the amount of heat that uh that coolant system can remove so this would be the coolant or the heat heat removed
removed so what do we have here so we have this line representing the heat being removed and then if you have a higher temperature difference between the coolant water and the reactants then more heat will be removed now also if you have a higher temperature you also have a higher increase in the in the kinetic constant or the rate of reaction so you also have a greater generation of heat so we have these two points we have point one and point two now point one is called the stable point so this is stable stable and
if you have this system let's say you just have the system set up if you have your reaction right here it's generating more heat than the than the coolant system is REM moving so it will it actually be it will actually increase the temperature of the system so it'll move this way and there'll come a point where it just hits this point where if we go right here if the system wants to try to move forward again well now more heat is being removed than generated so it will go back down this way so that's
why it's stable it will always kind of bounce around this area if it's if the reaction starts going off then more heat will be removed and it will go back to this one point now this point is the unstable Point any point in here if the reaction is anywhere on in here in this area or actually below this temperature I guess it's a big thing below this temperature it will go back to back to 0.1 however if it goes above Point 2 more heat will be generated than can be removed and this is where we
have a runaway reaction run away reaction action and that's just because more heat is being generated than can be removed by the heating system so this is the unstable Point uh unstable point
