Question

Consider the following reactions at 1000°C
(A) $Zn(s) + \frac{1}{2} O_2(g) \rightarrow ZnO(s)$; $\Delta G^0$ = -360kJmol⁻¹
(B) $C(gr) + \frac{1}{2} O_2(g) \rightarrow CO(g)$; $\Delta G^0$ = -460kJmol⁻¹
Choose the correct statement at 1000°C
(a) Zinc can be oxidized by carbon monoxide
(b) Zinc oxide can be reduced by graphite
(c) Both statements (A) and (B) are true
(d) Both statements (A) and (B) are false

Answer 1
