Consider the following equilibrium between \( \mathrm{N}_{2} \mathrm{O}_{4} \) and \( \mathrm{NO}_{2} \). Which changes would cause the reaction to become darker brown? Riew Available Hint(s) Run the reaction at a lower temperature. Decrease the volume of the container. Increase the pressure in the reaction vessel.

\( 2 LiOH ( s ) \rightarrow Li 2 O ( s ) + H 2 O ( l ) \)
