- (5) One of Prof Cunningham's former students wrote his doctoral dissertation about a new technology to clean up soil contaminated by certain types of chemicals. One of the chemicals we tested in the lab was 1,2,4,5-tetrachlorobenzene (TECB). (a) Draw the chemical structure of 1,2,4,5-tetrachlorobenzene. (b) When we started working on the project, we thought maybe TeCB would be de- stroyed according to first-order kinetics, but we weren't sure. Below are two tables of actual data that the student collected in the laboratory. The two data sets were collected under different experimental conditions. For each of the two experiments, determine if the disappearance of TeCB is zero-order, first-order, second-order, or something else. Specify the value of the rate constant (ko, k1, or k2, as appropriate). Be sure to give the right units of k! Table 1: Concentration of TECB vs. time, experiment 1 time (min) Conc.
