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. \[ E_a = \Box \, \frac{\text{kJ}}{\text{mol}} \] (Note: There is a numerical input box for entering the activation energy value.)
