A) (THERMODYNAMICS). The reaction CaCO3 <-------> CaO + CO2 has a Enthalpy = 177.8 kj/mol and Entropy = 160.5 j/k mol. Set up the Gibbs energy equation (G) and calculate the Gibbs energy equation at 300 K and at 1300 K?

B) At what temperature is the reaction spontaneous? hint: be very careful with the units of enthalpy and units of entropy.
