JEE Main Chemistry question
The equilibrium constant for H₂(g) + CO₂(g) ⇌ H₂O(g) + CO(g) is 1.80 at 1000°C. If 1.0 mole of H₂ and 1.0 mole of CO₂ are placed in one litre flask, the final equilibrium concentration of CO at 1000°C will be:
Answer: (A)
Solution
x²/(1−x)² = 1.80 → x/(1−x) = 1.342 → x = 0.573 M.
