1) For this reaction,

SiCl₄ (l)+ 2H2O(g) <-> SiO₂ (s) + 4HCl (g) DeltaH = -127 KJ

Predict the effect increase (i), decrease(d) or no change(nc) that each change has on the QUANTITY for the equilibrium mixture. Assume that each change is applied separately to the system.

Change	Quantity	Effect
increase in pressure	amount of H2O	i, d or nc
decrease temp	amount of SiCl₄	i d or nc
increase temp	Kc	i d or nc
increase temp	amount of H2O	i d or nc
add H2O	amount of SiCl₄	i d or nc
add SiO₂	amount of HCl	i d or nc
add HCl	amount of SiO₂	i d or nc

Thank you!! I will mark your answer thumbs up!
