produced. This iodine will be converted into I3- which will react stoichiometrically with the thiosulfate. The thiosulfate to be used for titration was first standardized using KIO3 as the primary standard. KI crystals and sulfuric acid was added to the KIO3 solution one after the other. KI crystals should be added first or the solution may produce more O2 and add to the analyzed dissolved oxygen of the sample: The resulting solution was titrated right away with Na2S2O3 as the titrant and starch

Motor parameters used for simulation are given in Table 1. Tables 2 and 3 shows the GA-PID and ACO-PID controller’s parameters. the response of Kp‚ Ki and Kd parameters are summarized on table 4 which shows that the proportional controller “Kp” will have the effect of reducing rise time and will reduce the steady state error while the integral controller “Ki” will have the effect of eliminating the steady state error but will have the worst transient response on a system while the derivative

[20 points] An enzyme-catalyzed reaction (KM = 2.7 × 10−3 M) is inhibited by a competitive inhibitor I (KI = 3.1 × 10−5 M). Suppose that the substrate concentration is 3.6 × 10−4 M. How much of an inhibitor is needed for 65% inhibition? How much does the substrate concentration have to be increased to reduce the inhibition to 25%? Constants R = 8
