Question

Why is red hot iron reaction with steam are reversible?

Answer 1

reversible reaction is one which can be made to go in either direction depending on the conditions. If you pass steam over hot iron the steam reacts with the iron to produce a black, magnetic oxide of iron called triiron tetroxide, \(Fe_3O_4\).

3Fe(s)+4H2(g)→Fe3O4(s)+4H2(g)

Answer 2

Answer:

f steam is passed over red hot iron, it is converted into its magnetic oxide and hydrogen gas. If on the other hand, hydrogen is passed over heated magnetic oxide, it will change back to iron and steam. This reaction can be made to proceed in both directions, so it is called reversible reaction
