WebJan 15, 2024 · ln 2 k = t 1 / 2 It is because the half-life of a 1 st order reaction is independent of concentration that it is oftentimes used to describe the rate of first order processes (such as radioactive decay.) For a 2 nd order reaction, the half-life can be expressed based on the integrated rate law. 1 1 2 [ A] o = 1 [ A] o + k t 1 / 2 WebNov 7, 2024 · Rate = k [C 12 H 22 O 11]. Half-Life of a reaction (t 1/2): It is the time in which the concentration of a reactant is reduced to one half of its initial concentration. It is …

It is denoted by t 1/2. Derivation of half life period: We know that for first order reaction. K= t2.303log (a−x)a. or t= K2.303log (a−x)a. If t=t 1/2 and x= 2a. then t 1/2= K2.303log (a− 2a)a. t 1/2= K2.303log2.

In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant). goat simulator 3 wanted
