41 **Le Châtelier's Principle and System Shifts in Equilibrium Reactions****Introduction:**According to Le Châtelier's principle, a system at equilibrium will respond to a stress by shifting in the direction that relieves the stress. This principle explains how chemical reactions can be shifted from their equilibrium positions by changing the volume, temperature, or by adding/removing reactants or products.**Part A:****For the following systems at equilibrium:**1. **System A:** \[ 2\text{NOCl}(g) \rightleftharpoons 2\text{NO}(g) + \text{Cl}_2(g) \]**Effect of Changing Container Size:**- **Increase container size:** - **Decrease container size:** **System B:** \[ \text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g) \]**Effect of Changing Container Size:**- **Increase container size:** - **Decrease container size:** **Classify these changes by their effect:**- **Leftward shift**- **No shift**- **Rightward shift***Interactive Diagram:*There is an interactive element where learners can drag the options under each system to bins labeled "Leftward shift," "No shift," or "Rightward shift."**Part B:****For the following systems at equilibrium:**1. **System C:** \[ \text{CaCO}_3(s) \rightleftharpoons \text{CaO}(s) + \text{CO}_2(g) \quad \Delta H = +178 \, \text{kJ/mol} \]2. **System D:** \[ \text{PCl}_5(g) \rightleftharpoons \text{PCl}_3(g) + \text{Cl}_2(g) \quad \Delta H = -88 \, \text{kJ/mol} \]**Effect of Changing Temperature:**- **System C:** - Increase temperature - Decrease temperature- **System D:** - Increase temperature - Decrease temperature**Classify these changes by their effect:**- **Leftward shift**- **No shift**- **Rightward shift***Interactive Diagram:*This section
