Question

1.
The reaction CaCO3 = CaO + CO2(g) goes to completion in
lime kiln because
[MP PMT/PET 1988; CPMT 1990]
(a) of the high temperature
(b) CaO is more stable than CaCO3
(c) CaO is not dissociated
(d) CO, escapes continuously​

Answer 1

Answer:

Lime-kiln is an open vessel. In lime-kiln, the reaction CaCO3⇋CaO+CO2(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.
