what are the reaction steps of the reaction between ferric chloride with hydrogen at 600 degree celsius

The reaction between ferric chloride (FeCl3) and hydrogen (H2) at 600 degrees Celsius is a redox reaction. Here are the steps involved in the reaction:

1. Step 1: Formation of Iron(II) Chloride (FeCl2)
At the beginning of the reaction, the hydrogen gas (H2) dissociates into atomic hydrogen (H•) due to the high temperature. The ferric chloride also dissociates, yielding ferric chloride vapors (FeCl3(g)). The atomic hydrogen then reacts with ferric chloride to form iron(II) chloride (FeCl2) and hydrogen chloride (HCl):

2FeCl3(g) + 6H• -> 2FeCl2 + 6HCl

2. Step 2: Reduction of Iron(II) Chloride (FeCl2)
In the next step, the iron(II) chloride that was formed reacts with more hydrogen gas to further reduce the iron:

FeCl2 + H2 -> Fe + 2HCl

This reaction reduces the iron(II) chloride to metallic iron (Fe) while simultaneously producing hydrogen chloride as a byproduct.

Overall, the balanced equation for the reaction between ferric chloride and hydrogen at 600 degrees Celsius is:

2FeCl3(g) + 6H2 -> 2Fe + 6HCl
