For the following equilibrium system, which of the following changes will form more CaCO3?
CO2(g) + Ca(OH)2(s) <--> CaCO3(s) + H2O(l)
deltaH(rxn) = -113 kJ

My choices are:
a) Decrease temperature at a constant pressure (no phase change)

B) Increase volume at a constant temperature

C) Increase partial pressure of CO2

D) Remove one-half of the initial CaCO3

I was thinking that it would be A, C, and D. Is that correct?
