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

A

Zn can be oxidised by CO

B

ZnO can be reduced by ''C''

C

CO can be reduced by ''Zn''

D

Both (1), (2) true

Text Solution

Verified by Experts

The correct Answer is:
