As to whether or not Fe3O4 is formed directly, that is doubtful since it would require an activated complex of three iron atoms and four water molecules -- very unlikely.
Which Of The Following Will Increase The Rate Of Backward Reaction In A Reversible Reaction? 2. It means the product is Fe 3 O 4 only. This reaction is carried out at room temperature in the presence of aluminum chloride or iron and in the absence of UV light. 3Fe + 4H 2 O -----> Fe 3 O 4 + H 2 . 1. Iron reacting with steam produces a familiar result, creating a layer of hydrated iron oxide over the iron, which then releases hydrogen into the surrounding area. 4 5 The reactors are run adiabatically in multiple reactors with steam added before each stage with typical yields of 88-94%. Again, if this reaction is carried out in an open vessel the whole of Fe30 4 is reduced to iron because one of the products, i.e., water escapes as steam. Reaction between iron and steam is reversible if it is carried out Ask for details ; Follow Report by Pandey9316 18.01.2018 Log in to add a comment Reversible reactions In some chemical reactions, the products of the reaction can react together to produce the original reactants . By passing steam over iron at about 1000K, we got magnetic oxide of iron called ferrosoferric oxide Fe 3 O 4 and H 2. Substitution Reaction. Know answer of objective question : Reaction between iron and steam is reversible if it is carried out_____.3Fe 4H2O —> Fe3O4 4H2. These reactions are called reversible reactions . $\begingroup$ Single displacement reactions do involve redox -- the element on the reactant side ends up in a combined state in the products and, therefore, must undergo a change of oxidation state. (Points : 1) Increase In Concentration Of One Of The Reactants Decrease In Concentration Of One Of The Products Increase In Concentration Of One Of The Products None Of The Above Question 2. Substitution reaction between methylbenzene and chlorine or bromine are take place in two ways: Substitution into the ring; Substitution into the methyl group; Substitution into the ring. The reactions in which products can react to give back reactants are called reversible reactions. Answer this multiple choice objective question and get explanation and result.It is provided by OnlineTyari in English If this reaction is carried out in open vessel then hydrogen gas escapes and reaction proceeds to completion.
Steam is used to provide heat of this reaction, to prevent excessive coking or carbon formation, to shift equilibrium of the reversible reaction towards the products, and to clean the catalyst of any carbon that does form.
