The above chemical equation 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 distinctive conditions for this reaction are high temperature and pressure. The reaction is usually conducted at a temperature of about 500-600 degrees Celsius and pressure from 1 to 3 atm. Additionally, a catalyst such as nickel is needed to accelerate the reaction.
- Reaction process
The reaction process takes place when iron(III) oxide and hydrogen are introduced together in a high temperature and pressure environment. The iron(III) oxide is converted to iron through a reduction process by hydrogen, while hydrogen is oxidized to water.
- Occurring phenomena
When the reaction occurs, we can observe a colour change. Iron(III) oxide is a reddish-brown colour, but after the reaction, the produced iron has a silvery-grey colour. Additionally, due to the reaction taking place at high temperatures, steam may be generated from the reaction.
