WebAnswer. The rate law is second order overall. The rate constant, by definition, is independent of concentrations, initial or otherwise, so ( a) must be true. The units of the rate constant for a second order reaction are M –1 s –1 or M –1 min –1 (rate = Ms –1 = k [M] [M]) so ( b) is false. 9. property people ltd belfastWebportrayed in his Figure 6.2. If, for example, isotope ahas a considerably longer half-life, the linear tail of the log-linear plot of A can be extrapolated backward to isolate Aa 0. The slope of this line also yields λ a.
