Reaction rate vs specific rate constant
WebKinetics: 6.32 - The rate constant. Significance of the rate constant. The rate constant, k, gives a direct measure of the relative reaction rate. A very small value for the rate constant equates to a very slow reaction in general. Equally, a large value for the rate constant means a large value for the rate and that the reaction is rapid. WebFor example, in the case of CH3OH synthesis at the Zn/Cu/Al2O3, the real temperature dependence of the rate constant of the RDS is almost zero and the temperature dependence of the reaction rate ...

WebIf we let [A] = the concentration of cyclopropane, the integrated rate law is [A] = [A]₀e^ (- k t) A plot of [A] vs. t is a curve that starts at [A]₀ and gradually approaches the horizontal axis asymptotically as t increases. The shape of the curve is called an exponential decay curve. WebJun 4, 2015 · We can also write it like this: R = k[A]1 The index 1 is referred to as the "order of the reaction" so we can describe this as a "first order reaction". The specific rate constant is defined as the rate of reaction when all the concentrations are equal to 1. If [A] = 1 you can see that R = k. Answer link
