Answer to: What is the rate constant of a first-order reaction that takes 536 seconds for the reactant concentration to drop to half of its initial...
Rate constant k : The rate constant k is equal to the rate of reaction when the concentration of the reactant in unity. It depends upon the order of reaction as well as temperature: Unity for k : (i) for a zero order reaction : mol L^(-1)s^(-1
The rate constant for a reaction is nearly doubled with about 10∘ rise in temperature. The reason is that the number of effective collision becomes almost double. The exact dependence of the rate of reaction can be given by Arrhenius equation, k=Ae−Ka/RT. Where, A is called the fre...
e) What is the proportionality constant ε l, in Beer’s law, abs = ε l [dye]? Include units in your answer. (Abs is unitless and [dye] is in mol/L or M.) f.) Calculate the rate constant (k) for the reaction of Yellow 6 with...
It is in relation to the rate constant of a reaction. For a first-order reaction, the half-life is {eq}t_{{1}/{2}} = \dfrac{\ln 2}{k} {/eq} Where {eq}k {/eq} is the rate constant. Answer and Explanation: Given: The rate constant is {eq}k=...
