Question

The free energy change for the following reactions are given below,
$C_2H_2(g) + \frac{5}{2}O_2(g) \rightarrow 2CO_2(g) + H_2O(l)$; $\Delta G^0$ = -1234kJ
$C(s) + O_2(g) \rightarrow CO_2(g)$; $\Delta G^0$ = -394kJ
$H_2(g) + \frac{1}{2} O_2(g) \rightarrow H_2O(l)$; $\Delta G^0$ = -237kJ
What is the standard free energy change for the reaction
$H_2(g) + 2C (s) \longrightarrow C_2H_2(g)$
(a) – 209 kJ
(b) –2259 kJ
(c) + 2259 kJ
(d) 209 kJ
