How are reaction rate laws derived? - Chemistry Stack Exchange
WebJan 30, 2015 · rate = k[A]2. The rate is proportional to the square of the concentration. If you double the concentration, you multiply the rate by four. If you triple the concentration, you … WebAs described earlier, rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions. The balanced equations most often encountered represent the overall change for some chemical system, and very often this is the result of some multistep reaction mechanisms. new hampshire by population

WebWhen the rate-determining step is preceded by a step involving an equilibrium reaction, the rate law for the overall reaction may be more difficult to derive. The following general mechanism example will illustrate how to derive overall rate laws from mechanisms involving equilibrium steps preceding the rate-determining step. WebJan 17, 2024 · When writing the rate law of a mechanism, we need to identify the rate-determining step. The rate-determining step is the slowest step of a mechanism.
