Question
At total pressure P₁ atm and P₂ atm, N₂O₄ is dissociated to an extent of 33.33% and 50.00%, respectively. The ratio of pressures P₁ and P₂ is
Answer: C
💡 Solution & Explanation
K_p = 4α²P / (1-α²) remains constant. For α₁ = 1/3: K_p = 4(1/9)P₁ / (8/9) = P₁/2. For α₂ = 1/2: K_p = 4(1/4)P₂ / (3/4) = 4P₂/3. Equating them: P₁/2 = 4P₂/3. Therefore, the ratio P₁/P₂ = 8/3. Therefore, correct answer is C.
