QUESTION 2 A student carried out the decomposition of nitrogen dioxide and measured the concentration of all species over for 400 seconds. The graph below shows the concentrations of all species at each time interval. 2 A+B C + 2D Experiment [A] (M) [B] (M) Initial Rate of formation of C (M s') 9.50 * 10- 1 0.10 0.20 2 0.20 0.20 1.90 103 3 0.30 0.40 1.14 x 10-2 4 ?? 0.15 2.68 x 10-4 a. Determine the initial rate of disappearance of reactant A in experiment 1. b. Determine the order of the reaction with respect to each reactant listed below. Show your work. i. for A and for B c. For the reaction i. write the rate law that is consistent with the calculations in part (b) ii. determine the overall order of the reaction and calculate the value of the specific rate constant, k, and specify its units d. Calculate the initial concentration of A, [A], in experiment 4
