According to Le Chatelier's principle, an equilibrium is subjected to any kind of stress then the equilibrium shifts in the direction of nullify the applied stress.
NH4HS (s) <======> NH3(g) + H2S(g)
The given reaction is endothermic reaction. If temperature is increased then equilibrium would shift in forward direction.
If more NH4HS is added to the flask, then equilibrium would shift in forward direction.
If some additional NH3 is added to the flask, then equilibrium would shift in backward direction.
If some H2S is removed from the flask, then equilibrium would shift in forward direction. So, pressure of NH3 would be increased.
