Question
At 1800 K, the equilibrium constant is \( K_{eq} = 1.03 \times 10^{-4} \) for the reaction \( \text{N}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{NO}(g) \).

**Question:**

What is the equilibrium partial pressure of NO in air, which has an initial total pressure of 1.000 atm if the composition of air is 80.0 percent \( \text{N}_2 \) and 20.0 percent \( \text{O}_2 \)?

**Answer Options:**

- \( \bullet \) 0.004009 atm
- ○ 0.0113 atm
- ○ 0.403 atm
- ○ 0.00202 atm
- ○ 0.0406 atm
