7.18 use mathematical soft ware or an electronic spreadsheet to examine the time dependence of [i] in the reaction mechanism a → i → p (ka, kb) by plotting the expression in eqn 7.12. in the following calculations, use [a]0 = 1 mol dm−3 and a time range of 0 to 5 s. (a) plot [i] against t for ka = 10 s−1 and kb = 1 s−1. (b) increase the ratio kb/ka steadily by decreasing the value of ka and examine the plot of [i] against t at each turn. what approximation about d[i]/dt becomes increasingly valid?
