(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.
