1.

According to the following diagram, which of the following option is correct?

Answer»

B can reduce `CO_(2)` above `800^(@)C`
C can reduce `AO_(2)` below `600^(@)C`
Both B and A can reduce CO2 above `400^(@)C`
A can reduce both `BO_(2)` and `CO_(2)` below `600^(@)C`

Solution :(i) `A+BO_(2)rarrAO_(2)+B,""Delta_("rxn")G^(@)`
(ii) `A+CO_(2)rarrC+AO_(2),""Delta_("rxn")G^(@)`
Below `600^(@)C, Delta_("rxn")G^(@)` for both the reaction (i) and (ii) is negative.
