Question

Between c and co which is better reducing agent at 673k

Answer 1

Answer:

At 673 K, the value of ΔG(co,co2) is less than that ofΔG(c,co). Therefore, CO can be oxidised more easily to CO2 than C to CO. Hence, CO is a better reducing agent than C at 673 K.

$\huge\bold\red{ CO }$ is a better reducing agent than C because

• At 983 k, the curves for the standard free energy formation of ${CO}_{2}$ from CO and C intersect at ∆G° involving change of C to ${CO}_{2}$ which means at this temperature or below this temperature CO is better than C.
