Question

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?
