Question

Consider the following reaction: CaCO3(s)→CaO(s)+CO2(g). Estimate ΔG∘ for this reaction at each of the following temperatures. (Assume that ΔH∘ and ΔS∘ do not change too much within the given temperature range.)

Part A 315 K ΔG∘ Δ G ∘ = nothing kJ

Part B 1085 K ΔG∘ Δ G ∘ = nothing kJ

Part C 1465 K ΔG∘ Δ G ∘ = nothing kJ

Part D Predict whether or not the reaction in part A will be spontaneous at 315 K . Predict whether or not the reaction in part A will be spontaneous at 315 . spontaneous nonspontaneous

Part E Predict whether or not the reaction in part B will be spontaneous at 1085 K . Predict whether or not the reaction in part B will be spontaneous at 1085 . spontaneous nonspontaneous

Part F Predict whether or not the reaction in part C will be spontaneous at 1465 K . Predict whether or not the reaction in part C will be spontaneous at 1465 . spontaneous nonspontaneous
