Question

un the equilibrium NH4HS = NH3+H2S the forward reaction can be favoured by
1) adding some more NH4HS
2) adding some more NH3
3)removing some ammonia from the reaction mixture
4)adding some more H2S​

Answer 1

Answer:

3. removing some ammonia from the reaction mixture

Explanation:

adding NH4HS doesnt do anything as its solid ...dont take part in equilibrium constant
