### Understanding Shifts in Equilibrium for Endothermic Reactions#### For the following endothermic reaction system at equilibrium:\[ \text{Fe}_2\text{O}_3 (s) + 3\text{H}_2 (g) \rightleftharpoons 2\text{Fe} (s) + 3\text{H}_2\text{O} (g) \]#### Choose the changes that will shift the equilibrium position to the left.(Select all that apply.)- [ ] Decrease temperature- [ ] Add \(\text{H}_2 (g)\)- [ ] Increase temperature- [ ] Add a catalyst- [ ] Remove \(\text{Fe}_2\text{O}_3 (s)\)- [ ] Remove \(\text{H}_2 (g)\)- [ ] Decrease volume#### Explanation of the Impact of Changes on Equilibrium:1. **Decrease Temperature**: In an endothermic reaction, decreasing the temperature shifts the equilibrium to the left as the system will try to produce more heat.2. **Add \(\text{H}_2 (g)\)**: Adding more of the reactant \(\text{H}_2\) would shift the equilibrium to the right to consume the extra reactant, not to the left.3. **Increase Temperature**: Increasing the temperature shifts the equilibrium to the right in endothermic reactions, as the system absorbs the additional heat.4. **Add a Catalyst**: Adding a catalyst does not shift the position of equilibrium; it only speeds up the rate at which equilibrium is reached.5. **Remove \(\text{Fe}_2\text{O}_3 (s)\)**: Removing a reactant shifts the equilibrium to the left to produce more of the reactant.6. **Remove \(\text{H}_2 (g)\)**: Removing \(\text{H}_2\) would shift the equilibrium position to the left to create more \(\text{H}_2\).7. **Decrease Volume**: Decreasing the volume increases the pressure. Since there are equal numbers of moles of gas on both sides (3 moles \(\text{H}_2\) on the reactant side and 3 moles \(\text{H}_2\text{O}\) on the product side), this change will
