The following system is at equilibrium:
2X(s)+4Y(g)⇌Z(g)
Classify each of the following actions by whether it causes a leftward shift, a rightward shift, or no shift in the direction of the net reaction.

Half the Volume
Remove Some X
Double the Volume
Add More X

  1. Half the volume means pressure is increased. An increase in P makes the reaction shift to the side with fewer mols. Fewer mols is on the right. So it shift to the right. By the way, DON'T count the 4X. X is a solid and doesn't enter into this.

    2. Removing some X has no effect AS LOG AS some solid remaions.

    3. Double volume. Reverse of 1.
    4. Add more X. Same answer as 2.
