Given :

\text{Fe}_2\text{O}_3(\text{s}) + 3\text{CO} \rightleftharpoons 2\text{Fe}(\text{s}) + 3\text{CO}_2

;

\Delta G_{25^\circ\text{C}} = -10 \text{ kJ}

What is the value of

\Delta G_{25^\circ\text{C}}

for

2\text{Fe}(\text{s}) + 3\text{CO}_2 \rightleftharpoons \text{Fe}_2\text{O}_3(\text{s}) + 3\text{CO}

(1) + 10 kJ (2) + 11.717 kJ (3) 8.28 kJ (4) 9.45 kJ
