Q. Carbon cannot reduce $Fe_2O_3$ to $Fe$ at a temperature below $983\, K$ because
KCET
KCET 2011
General Principles and Processes of Isolation of Elements
A
free energy change for the formation of $CO$ is more negative than that of $Fe_2O_3$
23%
B
$CO$ is thermodynamically more stable than $Fe_2O_3$
15%
C
carbon has higher affinity towards oxygen than iron
26%
D
iron has higher affinity towards oxygen than carbon
37%
Solution:
Below $983\, K$, conversion of iron to ferric oxide is more favourable.
