MCQ
The following reaction goes to completion in lime kiln because : $\mathrm{CaCO}_3 \rightleftharpoons \mathrm{CaO}+\mathrm{CO}_2(\mathrm{~g})$
  • A
    Of the high temperature.
  • B
    $\ce{CaO}$ is more stable than $\ce{CaCO_3}$.
  • C
    $\ce{CaO}$ is not dissociated.
  • ✓
    $\ce{CO_2}$ escapes continuously.
✓

Answer

Correct option: D.
$\ce{CO_2}$ escapes continuously.
In lime kilns, $\ce{CO_2}$​ formed continues to escape into the atmosphere and equilibrium is never established.
