Question
The thermal dissociation equilibrium of CaCO3(s) is studied under different conditions.
CaCO3(s) ⇋ CaO(s) + CO2(g)
For this equilibrium, the correct statement(s) is(are)
CaCO3(s) ⇋ CaO(s) + CO2(g)
For this equilibrium, the correct statement(s) is(are)
Options
A.ᐃH is dependent on T
B.K is independent of the initial amount of CaCO3
C.K is dependent on the pressure of CO2 at a given T
D.ᐃH is independent of the catalyst, if any
Solution
(A) (ᐃH)T2 - (ᐃH)T1 = (ᐃCP)r (T2 - T1)
(B) & (C) K depend only on temperature
(B) & (C) K depend only on temperature
