Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (c)2NO(g) + Cl₂(e) AG-41. KJ Now suppose a reaction vessel is filled with 1.42 atm of nitrosyl chloride (NOCI) and 0.768 atm of nitrogen monoxide (NO) at 928. °C. Answer the following questions about this system: Under these conditions, will the pressure of NO tend to rise or fall? Is it possible to reverse this tendency by adding Cl₂? In other words, if you said the pressure of NO will tend to rise, can that be changed to a tendency to fall by adding Cl₂? Similarly, if you said the pressure of NO will tend to fall, can that be changed to a tendency to rise by adding Cl₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of Cl₂ needed to reverse it. Round your answer to 2 significant digits.

![## Using Reaction Free Energy to Predict Equilibrium Composition
### Consider the Following Equilibrium:
\[ 2\text{NOCl}(g) \rightleftharpoons 2\text{NO}(g) + \text{Cl}_2(g) \quad \Delta G^\circ = +42.1 \text{ kJ} \]
Now suppose a reaction vessel is filled with 1.42 atm of nitrosyl chloride (NOCl) and 0.768 atm of nitrogen monoxide (NO) at 924 °C. Answer the following questions about this system:
1. **Under these conditions, will the pressure of NO tend to rise or fall?**
- Options:
- Rise
- Fall
2. **Is it possible to reverse this tendency by adding Cl₂?**
- Options:
- Yes
- No
3. **In other words, if you said the pressure of NO will tend to rise, can that be changed to a tendency to fall by adding Cl₂? Similarly, if you said the pressure of NO will tend to fall, can that be changed to a tendency to rise by adding Cl₂?**
- Options:
- Yes
- No
4. **If you said the tendency can be reversed in the second question, calculate the minimum pressure of Cl₂ needed to reverse it.**
