7. A reaction in which AB is converted to products, AB(g) → A(g) + B(g), was monitored as a function of time. The results are shown below: Time (s) [AB] (M) 0 0.950 50 0.459 100 150 250 300 0.302 0.225 0.149 0.128 350 400 450 500 0.112 0.0994 0.0894 0.0812 a. Using a computer graphing program (such as Excel) or graph paper, analyze and plot the data as appropriate to determine the order of the reaction. Briefly indicate your rationale for choosing the plots that you did. b. Write the rate law for this reaction, indicate the reaction order, and briefly explain your rationale. c. What is the value of the rate constant (k) for this reaction? Report your value with appropriate units, and indicate how you calculated the rate constant.
