The thermal dissociation equilibrium of CaCO 3 (s) is studied under different conditions.
For this equilibrium, the correct statement(s) is(are)
A
H is dependent on T
B
K is independent of the initial amount of CaCO 3
C
K is dependent on the pressure of CO 2 at a given T
D
H is independent of the catalyst, if any
Text Solution
Verified by ExpertsThe correct answer is:
A
(A, B, D)
For the equilibrium 
.
The equilibrium constant (K) is independent of initial amount of CaCO 3 where as at a given temperature is independent of pressure of CO 2 . Δ H is independent of catalyst and it depends on temperature.
Hence , and are correct.
