In a lime kiln, to get higher yield of CO ₂ , the measure that can be taken is

Options

  1. Ato remove CaO
  2. Bto add more CaCO ₃
  3. Cto maintain high temperature
  4. Dto pump out CO ₂

Correct answer

D. to pump out CO ₂

Step-by-step solution

In a lime kiln, to get higher yield of CO ₂ , the measure that can be taken is to pump out CO ₂ . This will reduce the pressure of CO ₂ and reaction will shift in forward direction. CaCO ₃ Heat CaO + CO ₂
