Expert Solution

C2H6(g)+7Cl2(g)→2CCl4(g)+6HCl(g)

ΔS∘rxn = ΔS∘f products - ΔS∘f reactants

= 6*186.9+2*309.85 - (229.6+7*223)

= -49.5J/mole-K

C2H6(g)+7Cl2(g)→2CCl4(g)+6HCl(g)

ΔG∘rxn = ΔG∘f products - ΔG∘f reactants

= 6*-95.3 + 2*-60.6 -(-32.82 + 7*0)

= -660.2KJ/mole

BaO(s)+CO2(g)→BaCO3(s)

ΔH∘rxn = ΔH∘f products - ΔH∘f reactants

= 112.1-(70.4 + 213.6)

= -171.9KJ/mole

BaO(s)+CO2(g)→BaCO3(s)

ΔG∘rxn = ΔG∘f products - ΔG∘f reactants

= -1137-(-520.4 -394.4) = -222.2KJ/mole
