(A) ΔH‌2 - ΔH‌1 = C‌P(min) (T‌2 - T‌1)
and C‌P depends on temperature. Hence enthalpy also depends on temperature.
(B) CaCO‌3(s) ⇌ CaO‌(g) + CO‌2(g)  K‌p = (P‌CO2)‌atequlibrium
For a given reaction,
Keq. depends only on temperature.
(C) Keq depends only on temperature.
(D) Enthalpy of reaction is independent of the catalyst.Catalyst generally changes activation energy.
