Question
![The rate constant \( k \) for a certain reaction is measured at two different temperatures:
\[
\begin{array}{|c|c|}
\hline
\text{temperature} & k \\
\hline
228.0 \, ^\circ \text{C} & 1.6 \times 10^8 \\
175.0 \, ^\circ \text{C} & 2.6 \times 10^7 \\
\hline
\end{array}
\]
Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy \( E_a \) for this reaction.
Round your answer to 2 significant digits.
\[
E_a = \boxed{\phantom{000}} \, \frac{\text{kJ}}{\text{mol}}
\]
Additionally, there is a box for entering the answer with options for multiplying by a power of ten and buttons for confirming or resetting the input.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa60cc6ce-11de-444a-af29-e9eb1b50e640%2F3d08c8d2-ead8-4064-9c21-66aec8f7eb95%2F5g1ccgq_processed.png&w=3840&q=75)
