Reaction between iron and steam is reversible if it is carried out
$$
3 \mathrm{Fe}+4 \mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{Fe}_{3} \mathrm{O}_{4}+4 \mathrm{H}_{2}
$$
  1. at constant $\mathrm{T}$
  2. at constant $\mathrm{P}$
  3. in an open vessel
  4. in a closed vessel

Solution

In an open vessel $\mathrm{H}_{2}$ gas will escape. So the reaction will be reversible if it is carried out in a closed vessel.
