**Transcription for Educational Website:** --- **Determining Standard Reaction Enthalpy** **Task:** Use the following data on the reaction \( \text{H}_2(\text{g}) + \text{Cl}_2(\text{g}) \rightarrow 2\text{HCl}(\text{g}) \) to determine the standard reaction enthalpy. | T/K | 300 | 500 | 1000 | |------|--------------|--------------|------------| | K | \(4.0 \times 10^{31}\) | \(4.0 \times 10^{18}\) | \(5.1 \times 10^8\) | **Note:** You are required to make a plot and use all the available information in the table to solve this problem. You can use any available software to make this plot, including spreadsheet programs, graphing calculators, or any appropriate data analysis tools. **Instructions:** 1. Plot the equilibrium constant \( K \) versus temperature \( T \). 2. Analyze how equilibrium constant \( K \) changes with temperature. 3. Use the plot to infer the enthalpy change of the reaction. --- **Diagram Explanation (if necessary):** In the provided table, \( T \) represents temperature in Kelvin (\( \text{K} \)), and \( K \) represents the equilibrium constant for the reaction. The values of \( K \) are given for three different temperatures: 300 K, 500 K, and 1000 K. To determine the standard reaction enthalpy, you can utilize the van 't Hoff equation which relates the change in the equilibrium constant (\( K \)) with temperature to the enthalpy change (\( \Delta H^\circ \)).
