Question

. (i) Write the reaction of steam with red hot iron. (ii) Why is this reaction considered a reversible reaction ? (iii) How can the reaction proceed continuously? Can you help me with bit 3​

Answer 1

Answer:

i) 3Fe + 4H2O ⇋ Fe3O4 + 4H2

ii) This reaction is reversible because if hydrogen formed is not removed, then the iron oxide formed is reduced back to iron.

iii) This reaction is reversible. If the hydrogen formed is not removed the iron oxide formed is reduced back iron. Thus, the reaction can proceed continuously.

Hope this helps!

Answer 2

1. The reaction of steam with a red hot iron is written as:

   3Fe + 4H2O → Fe3O4 + 4H2.

When steam is passed over red-hot iron, iron oxide with the release of hydrogen gas is formed.

2. This reaction of steam can be considered a reversible reaction because the iron oxide formed will be reduced back to iron, if the hydrogen formed is not removed.

3. The reaction is reversible and hence it can proceed continuously.
