How do I do Part B and Part C?

Submit Previous Answers Learning Goal: To learn how graphs can be used to answer kinetics questions. A student collected time (t) and concentration ([A]) data at 295 K for the reaction 2A-B. These time and concentration data are shown in the table to the right. The student then plotted graphs of Al versus t (Figure 1), In [A] versus t (Figure 2), and i/[A] versust (Figure 3). Correct Now that we know that the reaction is first order, we can determine the units of the rate constant. Part B What is the value of the rate constant for this reaction? Express your answer to three significant figures and include the appropriate units.
