Solid ammonium nitrite is added to an initially evacuated container. It decomposes according to the chemical equilibrium,
$NH_4NO_2(s) \rightleftharpoons N_2(g) + 2H_2O(g)$.
Which of the following statements are FALSE regarding this equilibrium?
Pumping additional $N_2(g)$ into the container increases the amount of solid ammonium nitrite.
Reducing the volume of the container increases the amount of $NH_4NO_2(s)$.
The partial pressure of water in the container is twice that of nitrogen.
Removing water (via a drying agent) does not affect the amount of $NH_4NO_2(s)$.
Adding more $NH_4NO_2(s)$ to the container does not affect the partial pressure of $N_2(g)$.
