Consider the following system at equilibrium where $K_c$ = 10.5 and $\Delta H^\circ$ = -18.8 kJ/mol at 350 K.
$2CH_2Cl_2(g) \rightleftharpoons CH_4(g) + CCl_4(g)$
The production of $CH_4(g)$ is favored by:
1. increasing the temperature.
2. increasing the pressure (by changing the volume).
3. increasing the volume.
4. removing $CH_2Cl_2$. False
5. adding $CCl_4$. False
