4. [Exam 2001] The concentrations of reactant A as well as products Rand S were monitored continuously in a batch reactor. The following two figures show the concentration-time curves and the instantaneous yield curves (or and @s). 10 10 08 081 OOO OG 0.6 06 Concentration 04 04 00000 02 02 00000000000000000000000 00 0.0 00 00 0.4 10 02 04 06 08 10 Time CA (a) Which of the following reaction systems is consistent with the experimental data? (i) AR+S ra= -KACA" (m>0) (ii) ARS rau-kaca" and rs = kscr" (m, n > 0) (iii) A Rand AS rr = kRCA" and rs = ksca" (m, n > 0) (b) Describe how the instantaneous yield curves are obtained from the raw data shown in the concentration-time curves and, if applicable, what is the relative magnitude of the reaction orders suggested by the given data? (c) If R is the desired product, recommend with reasons the most suitable type of reactor for the reactions. (d) It is found that the instantaneous yield of R, or increases with temperature. What can you deduce from this information on the reaction rate constants
