![**Using the Arrhenius Equation to Calculate Ea from k versus T Data**
The rate constant \( k \) for a certain reaction is measured at two different temperatures:
| Temperature (\( °C \)) | \( k \) |
|-----------------------|---------|
| 381.0 | \( 4.8 \times 10^{10} \) |
| 281.0 | \( 2.3 \times 10^{10} \) |
Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy \( E_a \) for this reaction. Round your answer to 2 significant digits.
\[ E_a = \, \text{ } \text{kJ/mol} \]
[Input Field:](Multiply by 10)
[Explanation] [Check]
**Diagram Explanation:**
There is a table that displays two temperature values in degrees Celsius alongside their corresponding rate constants \( k \) in scientific notation.
Below the table, there is a prompt to calculate the activation energy, \( E_a \), using the Arrhenius equation. An input field is provided for the answer, with a direction to multiply by 10 if necessary.
