When heated, CaCO, decomposes into CaO and CO₂ according to the following equation: CaCO,(s)=CaO(s)+ CO,(g) This is an endothermic reaction in which AH° = 178.3 kJ/mol and in which entropy increases, AS° = 159 J/mol K. To what temperature (in °C) must CaCO be heated in a closed container in order to produce CO₂ at an equilibrium pressure of 0.100 atm? (Assume AH° and AS do not change appreciably with temperature).
