### Chemical Equilibrium Problems

#### 3. Reaction Analysis

**Reaction:**  
\[ \text{Br}_2(g) + \text{Cl}_2(g) \rightleftharpoons 2 \text{BrCl}(g) \]

**Equilibrium Constant (K\_p):**  
\[ K\_p = 1.11 \times 10^{-4} \, \text{at 150 K} \]

**Initial Conditions:**  
- Partial pressure of Br\(_2\) = 0.993 atm
- Partial pressure of Cl\(_2\) = 0.967 atm

**Task:**  
Calculate the equilibrium partial pressures of Br\(_2\), Cl\(_2\), and BrCl at 150 K.

#### 4. Reaction Analysis

**Reaction:**  
\[ \text{CO}(g) + \text{H}_2\text{O}(g) \rightleftharpoons \text{CO}_2(g) + \text{H}_2(g) \]

**Equilibrium Constant (K\_p):**  
\[ K\_p = 0.0611 \, \text{at 2000 K} \]

**Initial Conditions:**  
- Partial pressure of CO = 1.768 atm
- Partial pressure of H\(_2\)O = 2.324 atm

**Task:**  
Calculate the equilibrium partial pressures of CO, H\(_2\)O, CO\(_2\), and H\(_2\) at 2000 K.

---

**Instructions for Solving the Problems:**

1. **Write the expression for K\_p:** Based on the reaction equations, write the expression for K\_p using the ratio of products to reactants, each raised to the power of their coefficients in the balanced equation.

2. **Use an ICE Table:** Set up an ICE (Initial, Change, Equilibrium) table to help visualize changes in partial pressures from initial conditions to equilibrium.

3. **Solve for Changes (x):** Use algebraic methods to solve for changes in pressure (\(x\)) and determine the equilibrium pressures.

4. **Calculate Equilibrium Pressures:** Use \(x\) to find the equilibrium pressures for each substance.

5. **Verify Results:** Ensure your calculated pressures satisfy the K\_p expression.
