The volume occupied by the reaction SiF4(g)+2H2O (g)=SiO2 (s)+4HF (g). is reduced.Predict the direction of shift in the position of equilibrium.Will the shift be in the direction of the more gaseous molecules,or fewer?

Answer 1

the shift will be to relieve the stress. The pressure stress is on the right side, so the the shift is to the left.

Answer 2

The volume occupied by the reaction SiF4(g)+2H2O (g)=SiO2 (s)+4HF (g).
