**Equilibrium and Partial Pressures** **Understanding Chemical Equilibrium**In this section, we will explore the concept of equilibrium constants (Kp) concerning a chemical reaction and how to use them.**Example Reaction and Given Data:**The equilibrium constant, \( K_p \), for the following reaction is \( 2.20 \times 10^4 \) at 723K.\[ 2\text{NH}_3(g) \rightleftharpoons \text{N}_2(g) + 3\text{H}_2(g) \]If an equilibrium mixture of the three gases in a 14.3 L container at 723K contains NH\(_3\) at a pressure of 0.743 atm and N\(_2\) at a pressure of 0.867 atm, calculate the equilibrium partial pressure of H\(_2\).**Steps to Calculation:**1. **Identify the Reaction Equation and Kp Expression:** \[ K_p = \frac{P_{\text{N}_2} \cdot (P_{\text{H}_2})^3}{(P_{\text{NH}_3})^2} \]2. **Plug in the Known Values:** \[ P_{\text{NH}_3} = 0.743 \text{ atm} \] \[ P_{\text{N}_2} = 0.867 \text{ atm} \] \[ K_p = 2.20 \times 10^4 \]3. **Solve for the Unknown Partial Pressure \( P_{\text{H}_2} \):** Rearrange the equation to solve for \( P_{\text{H}_2} \): \[ 2.20 \times 10^4 = \frac{0.867 \cdot (P_{\text{H}_2})^3}{(0.743)^2} \]4. **Detailed Algebraic Steps:** Multiply both sides by \((0.743)^2\): \[ 2.20 \times 10^4 \cdot (0.743)^2 = 0.867 \cdot (P_{\text{H}_2})^3 \] \[ 2.20 \times 10^4 \cdot 0.552049 = 0.867 \

While ethanol (CH3CH₂OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene (CH₂CH₂) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 500. mL flask with 0.80 atm of ethylene gas and 4.2 atm of water vapor. When the mixture has come to equilibrium she determines that it contains 0.42 atm of ethylene gas and 3.82 atm of water vapor. The engineer then adds another 0.27 atm of ethylene, and allows the mixture to come to equilibrium again. Calculate the pressure of ethanol after equilibrium is reached the second time.

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 1.5 L flask with 2.4 atm of nitrogen dioxide gas. When the mixture has come to equilibrium she determines that it contains 1.5 atm of nitrogen dioxide gas. The engineer then adds another 0.60 atm of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the pressure of dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to 2 significant digits. atm x10
