A vessel at 1000 K contains \( \text{CO}_2 \) with a pressure of 0.5 atm. Some of \( \text{CO}_2 \) is converted into \( \text{CO} \) on addition of graphite. If total pressure at equilibrium is 0.8 atm, then \( K_p \) is:
Show Hint
- 0.18 atm
- 1.8 atm
- 0.3 atm
- 3 atm
The Correct Option is B
Solution and Explanation
| Substance | \( \text{CO}_2 \) | \( C \) | \( \text{CO} \) |
|---|---|---|---|
| Initial Pressure (atm) | 0.5 | - | 0 |
| Change in Pressure (atm) | -x | - | +2x |
| Equilibrium Pressure (atm) | 0.5 - x | - | 2x |
