Consider the following reactions at 1000^(@)C (I) Zn(s)+1//2O_(2)(g)overset(Delta)to ZnO(g), Delta G^(@)= -360 " kJ mol"^(-1) (II) C(s)+1//2O_(2)(g) overset(Delta)to CO(g), Delta G^(@) = -460 " kJ mol"^(-1) and choose the correct statement at 1000^(@)C

Answer»

ZNO is more stable than CO
ZnO can be reduced to ZN by C
ZnO and CO are FORMED at equal rate
ZnO can not be reduced to Zn by C

Solution :From given reaction, Free energy of the reaction : `ZnO(g)+C(s) underset(1000^(@)C)overset(Delta)to Zn(g)+CO(g)`, is negative.
