Question

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 {A] versus t (Figure 1), ln [A] versus t (Figure 2), and 1/[A] versus t (Figure 3). Next, the student ran the same reaction at different temperature and measured a different reaction rate, with the following results: What is the activation energy of this reaction? Express your answer to three significant figures and include the appropriate units.
