NH4Cl(s) <=> NH3 (g) + HCl (g) when a mixture of these two gases are compressed to a smaller volume, which way does the reaction shift to? the reaction is originally at 588 kelvins and has an equilibrium constant of "k"=0.0180, does the increased pressure cause the reaction to shift to the formation of the solid? if so why?
