Write down the reactions taking place in Bast furnace related to the metallurgy of iron in the temperature range `500-800K`

Explanation

To solve the question regarding the reactions taking place in the blast furnace related to the metallurgy of iron in the temperature range of 500-800 K, we can outline the following steps:

### Step-by-Step Solution:

1. **Identify the main reactants**: In the blast furnace, the primary reactants for the extraction of iron are iron(III) oxide (Fe2O3) and carbon monoxide (CO).

2. **First Reaction**: At temperatures between 500-800 K, the first reaction involves the reduction of iron(III) oxide to iron(II,III) oxide (Fe3O4) using carbon monoxide:
\[
