Frank-Kamenetskii Equation

The Frank-Kamenetskii equation describes how the temperature of a reactive material changes when it undergoes a chemical reaction that releases heat. It helps predict whether a substance will cool down or heat up, potentially reaching a dangerous "runaway" temperature. Essentially, it balances heat produced by the reaction with heat lost to the environment, factoring in how reaction rates increase with temperature. This equation is important in safety and combustion studies, as it helps determine conditions under which a material might spontaneously ignite or sustain a controlled reaction.
