Question
At 444°C, HI is 30% dissociated. If initially 3 moles of HI are taken, the number of moles of HI at equilibrium is
Answer: B
💡 Solution & Explanation
Initial moles of HI = 3. Since it is 30% dissociated, the amount of HI that reacts is 0.30 × 3 = 0.9 moles. The moles of HI remaining at equilibrium is 3 - 0.9 = 2.1 moles. Therefore, correct answer is B.
