Consider the following system at equilibrium where
$\Delta H^\circ = 268 \, kJ$ and
$K_c = 5.10 \times 10^{-6}$, at 548 K.
$NH_4Cl(s) \rightleftharpoons NH_3(g) + HCl(g)$
The production of $NH_3(g)$ is favored by (indicate true or false):
increasing the temperature:
decreasing the pressure (by changing the volume):
increasing the volume:
adding $NH_4Cl$:
removing $HCl$:
