# Problem: Consider the following reaction occurring at 298 K: BaCO3(s) ⇌ BaO(s) + CO2(g)What temperature is required to produce a carbon dioxide partial pressure of 1.0 atm?

Step 1: We need to determine the ΔH˚rxn:

$\overline{){\mathbf{\Delta H}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{∆}}{{\mathbf{H}}}_{{\mathbf{f}}}{{\mathbf{°}}}_{{\mathbf{products}}}{\mathbf{-}}{\mathbf{∆}}{{\mathbf{H}}}_{{\mathbf{f}}}{{\mathbf{°}}}_{{\mathbf{reactants}}}}$

ΔH˚rxn = 271,500 J

Step 2: We need to determine the ΔS˚rxn:

ΔS˚rxn = 173.8 J/K

Step 3: We need to determine the ΔG˚rxn:

ΔG˚rxn = 0 J
