The partial pressure of carbon dioxide is 0.402 atm. Calculate the ΔG (in kJ) for the conversion limestone (CaCO3) to quicklime (CaO) at 797°C.
CaCO3 (s) → CaO (s) + CO2 (g)
ΔH° 298 (in kJ/mol) -1206.9 -635.5 -393.51
ΔS° 298 (in J/mol*K) 92.9 40.0 213.6
(Write answer in decimal form to two decimal places)
