Carbon can reduce ferric oxide to iron at a temperature above 983 K because

A

Free energy change for the formation of CO is more negative than that of `Fe_(2)O_(3)`

B

CO is thermodynamically more stable than `Fe_(2)O_(3)`

C

Carbon has higher affinity towards oxygen than iron

D

iron has higher affinity towards oxygen than carbon

Text Solution

Verified by Experts

The correct Answer is:
D

Below 983 K, conversion of iron to ferric oxide is more favourable .i.e., iron has higher affinity towards oxygen than carbon.

Two metal rods made up of iron (K_1=79Wm^(-1)K^(-1)) and brass (K_2=109Wm^(-1)K^(-1)) are of identical shape and size. These are fused at the junction. If the temperature at the free end of iron is at a steam point and brass at ice point then calculate the temperature at the junction, when the steady state is attained.
