Chapter 15, Problem 15.73QP

Heating solid sodium bicarbonate in a closed vessel establishes the following equilibrium.

${\text{2NaHCO}}_{\text{3}}\left(s\right)\rightleftarrows {\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(g\right)+{\text{CO}}_{\text{2}}\left(g\right)$

What would happen to the equilibrium position if (a) some of the CO₂ were removed from the system, (b) some solid Na₂CO₃ were added to the system, (c) some of the solid NaHCO₃ were removed from the system? The temperature remains constant.
