Question
The rate constant \( k \) for a certain reaction is measured at two different temperatures: | Temperature (°C) | \( k \) | |------------------|-----------------------| | 190.0 | \( 9.2 \times 10^{10} \) | | 316.0 | \( 8.5 \times 10^{11} \) | Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy \( E_a \) for this reaction. Round your answer to 2 significant digits. The diagram includes a formula box for entering the calculated activation energy, \( E_a \), in \( \text{kJ/mol} \). It also has a text input field with calculator controls for confirming or clearing the input.
