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)` :

Options

A. Removing some of `NH_(3)` form flask.
B. Removing some of `NH_(4)HS (s)`.
C. On increasing pressure by decreasing volume
D. Increasing temperature.

Answer

C

Explanation

(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.
