Solution
IF we observe the Ellingham diagram, the curve involving △G∘ (for CO \longrightarrow CO_2 and C \longrightarrow CO_2) vs T intersect each other at 983 K. △G∘(CO1CO2) is more as compared to△(C,CO2). It means that at 983 K or above, coke (C) is a better reducing atgent whereas below this temperature, the reverse is true (i.e. CO is better). Thus , Carbon monoxide (CO) is a better reducing agent at 673 K.
