Le chatliers principle and solids

[dnt]

im pretty sure i know the answer but want to be sure.

if you have a reaction such as :

A(g) + B(g) --> C(g) + D(s)

and you increase the concentration of A, the reaction will shift to the right.

and i know the concentration of B will decrease and C will increase.

but what about D. I am pretty sure it won't change because its a solid...is that correct? or does it increase because the shift is to the right?

Amount of D will increase, but we assume its concentration equals 1 all the time.
