Note: use Excel spreadsheet for all your calculations and round to the correct significant figure

Question 2 The data tabulated below were obtained for the decomposition reaction of a chemical compound at 50 C. From the amount of product collected, the conversion can be calculated and the data are: 0 Time (min) Conversion % 3 6 9 12 15 18 21 24 30 18.2 33.1 45.255.2 63.3 70.0 75.5 79.9 86.6 0 1 ekt First order reaction rate formula appeared to describe real reactions rates as: T-M a) Iffis the conversion fraction and t is the time in minutes, what are the unit of the constant k b) Fit a straight line to the above data to find the regression model constant k. CHENG111 - Introduction to Chemical Engineering 2021-22 S2 c) Use two point interpolation to find the time of decomposition reaction for 68 % conversion d) Use regression model to find the time of decomposition reaction for 68 % conversion e) Compare and comment on the answers obtained in c and d f) Which method you will use to find the conversion of decomposition reaction after 38 min and why
