Solution

The correct option is D $C O_{2}$ escapes continuously
Lime-kiln is an open vessel. In lime-kiln, the reaction $C a C O_{3} ⇋ C a O + C O_{2} (g)$ is irreversible. The carbon dioxide gas escapes in the atmosphere. Hence, only forward reaction occurs. The reaction continues to occur until all calcium carbonate is exhausted.
