Practice question

Given: The K_p for H₂(g) + CO₂(g) <=> H₂O(g) + CO(g) is 0.25 at 1000 K. What is K_c if R = 0.0821 L · atm · mol^{-1 · K^{-1 ? Formula: Δ n = (1 + 1) - (1 + 1) = 0, so K_p = K_c (RT)^{Δ n = K_c. Substitution & Calculation: Thus, K_c = K_p = 0.25 . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
