3.19 Parallel reactions. Consider the scheme shown, in which the point of interest is the study of (1), complicated by (2). The progress of the reactions was followed by monitoring [SCN^-] at various times.

19. Parallel reactions. Consider the scheme shown, in which the point of interest is the study of (1), complicated by (2). The progress of the reactions was followed by monitoring [SCN]at various times. 15 (a) Show that a plot of ln([SCN][SCN]t) versus time will be linear in experiments with [Fe2+][A]. What is its slope, which will be labeled k ? (b) Calculate the rate constants from an experiment with [A]0=9.1105M and [Fe2+]0=0.384M at 25.0C, which had [SCN]=7.8105M and an apparent rate constant of k=7.62105s1. 19. Parallel reactions.
