### Chemical Equilibrium Problem**Given Scenario:**When 1.0 mol of water vapor and 3.0 mol of carbon monoxide is allowed to reach equilibrium at 986°C (\(K_p = 0.63\)), the total pressure at equilibrium is 2.0 atm.The reaction is as follows:\[ \text{CO(g)} + \text{H}_2\text{O(g)} \rightleftharpoons \text{CO}_2\text{(g)} + \text{H}_2\text{(g)} \]**Questions:**a. What is the partial pressure of each gas at equilibrium?b. How many moles of each species are present at equilibrium?**Detailed Explanation for Students:**1. **Identify Initial Conditions:** - Initial moles of \(\text{CO}\) = 3.0 mol - Initial moles of \(\text{H}_2\text{O}\) = 1.0 mol - Allowed to reach equilibrium at a total pressure of 2.0 atm2. **Establish the Equilibrium Expression:** - For the reaction, the equilibrium constant \(K_p\) is given by: \[ K_p = \frac{P_{\text{CO}_2} \cdot P_{\text{H}_2}}{P_{\text{CO}} \cdot P_{\text{H}_2\text{O}}} = 0.63 \]3. **Assume the Change in Moles:** - Let \(x\) be the change in moles of each gas as it reaches equilibrium. - Initial \(\text{CO}\) moles = 3.0 mol, equilibrium moles = 3.0 - \(x\) mol - Initial \(\text{H}_2\text{O}\) moles = 1.0 mol, equilibrium moles = 1.0 - \(x\) mol - \(\text{CO}_2\) and \(\text{H}_2\) are initially 0 mol, equilibrium moles = \(x\) mol each4. **Express Total Pressure:** - Given total pressure at equilibrium = 2.0 atm5. **Calculate Partial Pressures:** - Let's denote the
