WebIf we plot the concentration of a reactant versus time, we can see the differences in half lives for reactions of different orders in the graphs. We can identify a 0, 1 st , or 2 nd order reaction from a plot of [A] versus t by the variation in the time it takes the concentration of a reactant to change by half. WebAug 8, 2024 · A first-order reaction (where order = 1) has a rate proportional to the concentration of one of the reactants. 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 ...
