Calcium oxide (CaO), also called quicklime is prepared bydecomposing limestone (CaCO3) in a kiln at high temperature and thereaction proceeds as: CaCO3 (s) ⇆ CaO (s) +CO2 (g)
Given :
At T= 25 °C, then T=298 K
ΔH° = +177.8 kJ/mol
ΔS° = +160.5 J/K mol
Calculate Gibbs Free Energy change (ΔG) for thereaction.
A.) +130.0 kJ/mol
B.) +160.5 kJ/mol
C.) -130.0 kJ/mol
D.) -160.5 kJ/mol
