Question
![The rate constant \( k \) for a certain reaction is measured at two different temperatures:
\[
\begin{array}{|c|c|}
\hline
\text{temperature} & k \\
\hline
73.0 \, ^\circ\text{C} & 5.9 \times 10^7 \\
-12.0 \, ^\circ\text{C} & 3.5 \times 10^6 \\
\hline
\end{array}
\]
Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy \( E_a \) for this reaction.
Round your answer to 2 significant digits.
\[
E_a = \Box \, \frac{\text{kJ}}{\text{mol}}
\]
