Question
### Chemical Thermodynamics and Energy Changes #### Understanding the Heat of Reaction (\(\Delta H\)) The **heat of reaction**, \(\Delta H\), is the amount of heat absorbed or released during a chemical reaction. It is calculated as the difference in energy between the products and the reactants. --- #### Problem Statement - **Chemical Reaction:** \(2\text{NH}_4\text{Cl}(\text{s}) + \text{Ba(OH)}_2 \cdot 8\text{H}_2\text{O}(\text{s}) \rightarrow 2\text{NH}_3(\text{aq}) + \text{BaCl}_2(\text{aq}) + 10\text{H}_2\text{O}(\text{l})\) - **Given:** The \(\Delta H\) for this reaction is \(54.8 \, \text{kJ}\). - **Task:** How much energy would be absorbed if \(25.1 \, \text{g}\) of \(\text{NH}_4\text{Cl}\) reacts? Express your answer with the appropriate units. --- #### Graphical Representation **Energy Diagram:** - The diagram displays the progress of the reaction on the x-axis and the energy level on the y-axis. - Point A represents the energy of the reactants. - Point D signifies the energy level of the products. - The peak labeled B shows the activation energy required for the reaction. - The vertical drop from B to D is marked as C, indicating the overall change in energy (\(\Delta H\)) as the reaction progresses from reactants to products. This visual representation helps illustrate the concept of activation energy and the energy changes (\(\Delta H\)) during the reaction. --- Please complete the task and submit your answer using the input fields provided.
