WebJan 26, 2015 · Nope, we are assuming it is a first order reaction because this reaction only has one step. And this step only has one reactant with a coefficient of 1. If this reaction has multiple steps, even if it has one reactant, the order of reaction may not … WebNov 11, 2024 · Calculate log (x/m) and log (c) for each beaker. Then make the following graph: plot log (c) against log (x/m). The linear relationship you will obtain will have 1/n as slope and log (K) as... WebAug 8, 2024 · The rate of a first-order reaction is proportional to the concentration of one reactant. A common example of a first-order reaction is radioactive decay, the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments. The rate law is: rate = k [A] (or B instead of A), with k having the units … crystal balti wordsley menu
