Question

Does the number of moles of reaction products increase, decrease or remain same when each of the given equilibria is subjected to a decrease in pressure by increasing the volume? 3Fe (s) + 4H₂O (g) ⇆ Fe₃O₄ (s) + 4H₂ (g)

Answer 1

The given chemical reaction is as follows- 3Fe(s) + 4H2O (g) -- Fe3O4(s) + 4H2 (g).

The number of moles here in the reaction will always remain the same according to the Le Chatelliers principle.

Here the number of moles of the gaseous products is equal to the number of gaseous reactants, and so the number of moles remains the same.
