Question
![The rate constant \( k \) for a certain reaction is measured at two different temperatures:
| Temperature (°C) | \( k \) (s\(^{-1}\)) |
|------------------|-------------------|
| 311.0 °C | \( 1.4 \times 10^{10} \) |
| 246.0 °C | \( 2.0 \times 10^9 \) |
Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy \( E_a \) for this reaction.
Round your answer to 2 significant digits.
**Equation to Calculate Activation Energy:**
\[ E_a = \square \, \text{kJ/mol} \]
