Consider the following reactions at `1000^(@)C`.
(A) `Zn_((s))+1/2 O_(2(g)) rarr ZnO_((s)), DeltaG^(@)=-360` kJ/mol
(B) `C_("(gra)")+1/2 O_(2(g)) rarr CO_((g)), DeltaG^(@)=-460` kJ/mol
correct statement at `1000^(@)C` is

Options

A. ZnO is more stable than CO
B. ZnO can be reduced to Zn by C
C. ZnO and CO are formed at equal rate
D. ZnO can not be reduced to Zn by C

Answer

B

Explanation

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