Use mathematical software or an electronic spreadsheet to examine thetime dependence of [i] in the reaction mechanism a →i→p (k1,k2). youmay either integrate eqn 22.39 numerically (seeappendix2) or use eqn 22.40directly. in all the following calculations, use [a]0=1 mol dm−3and a timerange of 0 to 5 s.
(a) plot [i] against tfork1=10 s−1andk2=1 s−1.
(b) increasethe ratio k2/k1steadily by decreasing the value of k1and examine the plot of [i]againsttat each turn. what approximation about d[i]/d'becomes increasingly value?

Two groups of students were asked how many hours they spent reading each day. the table below shows the numbers for each group: group a 1 2 1 1 3 3 2 2 3 group b 3 2 3 2 2 2 1 1 2 based on the table, which of the following is true? the interquartile range for group a students is 0.5 less than the interquartile range for group b students. the interquartile range for group a students is equal to the interquartile range for group b students. the interquartile range for group a employees is 0.5 more than to the interquartile range for group b students. the interquartile range for group a employees is 1 more than the interquartile range for group b students.
