The reaction represented by the equation C(s) + H2O(l) → CO(s) + H 2(s) was carried out at 27oC if the enthalpy change was + 4500 J and the entropy change was + 12J, what was the free energy change? (∆G = ∆H

The reaction represented by the equation C_(s) + H₂O_(l) → CO_(s) + H ₂_(s) was carried out at 27_oC if the enthalpy change was + 4500 J and the entropy change was + 12J, what was the free energy change? (∆G = ∆H - T∆S)

A - 4176 J
B +4176 J
C - 900 J
