Homework Statement


Suppose the reaction system UO2(s) +4HF(g) <-> UF4(g) +2H2O(l)
is sealed in a container and allowed to equilibrate at a particular temperature.

Explain what happens to the nature of each substance if you:
a. remove some UO2 from the system
b. remove all UO2 from the system


Homework Equations





The Attempt at a Solution


I know that UO2 is solid and that it does not affect the equilibrium but in my answers it says that a) will have no effect while b) will increase [HF] and decrease [UF4].....why is that? I thought that all solids will have no effect no matter how much you take out..Thanks.

Soilds have no effect as long as they exist. If the soid doesn't exist, system will shift the equilibrium till the solid appears.
