Ammonium bydrogen sulfied, NH_(4)HS is unstable at room temperature an – InterviewSolution

1.	Ammonium bydrogen sulfied, NH_(4)HS is unstable at room temperature and decomposes as : NH_(4)HS (s) hArr NH_(3) (g) + H_(2)S (g) Then which of the following will produce less H_(2)S (g) :
Answer» Removing some of `NH_(3)` form flask. Removing some of `NH_(4)HS (s)`. On increasing pressure by DECREASING volume Increasing TEMPERATURE. Solution :(1) Removing product will shift EQUILIBRIUM forward. (2) Adding or removing a SOLID doesn't effect equilibrium (4) Decomposition reactions are endothermic in nature, increasing temperature will shift equilibrium forward.
