**Using Le Chatelier's Principle to Predict the Result of Changing Conditions in a Chemical Equilibrium****Reaction:** Acetylene and oxygen react to form carbon dioxide and water, as shown: \[ 2 \text{C}_2\text{H}_2(g) + 5\text{O}_2(g) \rightleftharpoons 4\text{CO}_2(g) + 2\text{H}_2\text{O}(g) \]**Scenario:** Suppose a mixture of $\text{C}_2\text{H}_2$, $\text{O}_2$, $\text{CO}_2$, and $\text{H}_2\text{O}$ has come to equilibrium in a closed reaction vessel. Predict the change, if any, due to the following perturbations in the table, and determine whether the equilibrium shifts to the right or to the left.| Perturbation | Change in Composition | Shift in Equilibrium ||---------------------------------------|-----------------------|----------------------|| Some $\text{H}_2\text{O}$ is removed. | ? | ☐ to the right ☐ to the left ☐ (none) || The pressure of $\text{O}_2$ will: | ? | ☐ to the right ☐ to the left ☐ (none) || Some $\text{O}_2$ is added. | ? | ☐ to the right ☐ to the left ☐ (none) || The pressure of $\text{CO}_2$ will: | ? | ☐ to the right ☐ to the left ☐ (none) |**Explanation & Discussion:** Use Le Chatelier's Principle to evaluate how the system responds to each change. For example, removing $\text{H}_2\text{O}$ might shift the equilibrium towards the products to restore balance, while adding $\text{O}_2$ could push the equilibrium to the right to consume the excess reactants.**Action:** - Review each scenario.- Predict and check your answers using the principles of chemical equilibrium.**Note:** This is a hypothetical exercise to aid in understanding equilibrium responses in chemical reactions.

According to Le Chatlier's principle, a system in equilibrium tends to remain in equilibrium and…
