The chemical equation above describes the reaction between iron(III) oxide (Fe2O3) and hydrogen (H2) to produce iron (Fe) and water (H2O). In this reaction, iron(III) oxide and hydrogen are the reactants, while iron and water are the products.
- Reaction conditions:
The conditions for this reaction are that the temperature must be high enough (about 500-600 degrees Celsius), the reaction pressure is also relatively high and controlled, and the presence of catalysts such as Ni, Pt is necessary to improve the reaction rate.
- The reaction process:
When the temperature, pressure and the presence of the catalysts are sufficient, the iron(III) oxide molecules will react with the hydrogen molecules, producing metallic iron and water.
- Observable phenomena:
During the reaction, the dark red color of iron(III) oxide gradually turns to gray-black iron. Simultaneously, water forms in the form of steam due to the high temperature of the reaction.
