AI Generated Solution

To calculate the fraction of molecules having energy equal to the activation energy for the decomposition of hydrogen iodide at 581 K, we can use the Arrhenius equation. The relevant part of the equation we need is the term \( e^{-\frac{E_a}{RT}} \), which represents the fraction of molecules that have energy equal to or greater than the activation energy. ### Step-by-Step Solution: 1. **Identify the given values**: - Activation energy (\( E_a \)) = 209.5 kJ/mol - Temperature (T) = 581 K - Universal gas constant (R) = 8.314 J/(mol·K) ...
