Exothernic terminolgy

Exothernic terminolgy

Exothernic terminolgy

(OP)
Looking for a term I heard many years ago and my Google searching ability has lead to nothing:

Trying to find a term (or name of an engineering/physics/chemistry 'law') that indicates that the hotter a product is (or becomes) during an exothermic reaction, the greater the temperature rise accelerates...or something to that affect.

Any ideas? Seems like it was a 'law' named after someone...

Exactly It!!!!

Thank You...I knew someone on here would have it...

RE: Exothernic terminolgy

Arrhenius' equation is, for many common chemical reactions at room temperature, the reaction rate doubles for every 10 degree Celsius increase in temperature. In Transformer engineering, we use it as, for every 6 C rise in operating temperature, the insulation life is reduced by half.

RE: Exothernic terminolgy

Sounds to me like you are describing "thermal runaway", the condition where as the temperature increases, the heat generation also gets higher, so that the temperature goes up faster and faster until something breaks or melts or catches fire. I have seen this happen in poorly-designed power supplies.
