To calculate the activation energy (Ea) when the rate of a reaction doubles as the temperature increases from 298 K to 308 K, we can use the Arrhenius equation in its logarithmic form. Here’s a step-by-step solution: ### Step 1: Understand the relationship between rate constants and temperature When the temperature increases, the rate constant (K) of a reaction changes. In this case, we know that the rate doubles when the temperature rises from 298 K to 308 K. Therefore, we can express this as: \[ \frac{K_2}{K_1} = 2 \] where \( K_1 \) is the rate constant at 298 K and \( K_2 \) is the rate constant at 308 K. ### Step 2: Use the Arrhenius equation ...
