The reaction A+B+C was carried out in a constant-volume batch reactor where the following co centration measurements were recorded as a function of time. (min) 059 15 22 30 40 60 C₁ (mol/dm³) 2 1.6 1.35 1.1 0.87 0.70 0.53 0.35 (a) Use nonlinear least squares (i.e., regression) and one other method determine the reaction order a and the specific reaction rate. (b) If you were to take more data, where would you place the points? Why (c) If you were to repeat this experiment to determine the kinetics, wh would you do differently? Would you run at a higher, lower, or the san temperature? Take different data points? Explain. (d) It is believed that the technician made a dilution error in the concentr tion measured at 60 min. What do you think? How do your answe compare using regression (Polymath or other software) with tho obtained by graphical methods?
