The temperature of blast furnace to produce iron from its ore `Fe_(2)O_(3)` varies from `500^(@)C` at the top of the furance to about `1900^(@)C` at the bottom of the furance. The reaction between the ore `Fe_(2) O_(3)` and `CO` at the lowest temperature `(~500^(@)C)` is

Options

A. `3Fe_(2)O_(3) + CO rarr 2 Fe_(3) O_(4) + CO_(2)`
B. `Fe_(2) O_(3) + CO rarr 2 FeO + CO_(2)`
C. `Fe_(2) O_(3) + 3C) rarr 2Fe + 3CO_(2)`
D. `Fe_(2) O_(3) + CO rarr 2Fe + CO_(2) + (1)/(2) O_(2)`

Answer

C

Explanation

At `500^(@) FeO_(3)` is reduced by `CO` to `Fe` and `CO_(2)`.
