| \[N{{H}_{4}}HS\,(s)\,\rightleftharpoons \,N{{H}_{3}}(g)\,\,+\,\,{{H}_{2}}S(g)\] |
| If more \[N{{H}_{4}}HS\] is added to the equilibrium |
A) Partial pressure of \[N{{H}_{3}}\] increases
B) Partial pressure of \[{{H}_{2}}S\] increases
C) Total pressure in the container increases
D) No effect on partial pressure of \[N{{H}_{3}}\] and \[{{H}_{2}}S\]
Correct Answer: D
Solution :
\[N{{H}_{4}}HS(s)\,\,\rightleftharpoons \,\,N{{H}_{3}}(g)\,\,+\,\,{{H}_{2}}S(g)\] \[Kp=N{{H}_{3}}\left( g \right)\,\,\times \,\,{{H}_{2}}S\left( g \right)\] Partially pressure of \[N{{H}_{3}}\] and \[{{H}_{2}}O\] doesn?t affected by \[N{{H}_{4}}HS\left( s \right)\] because \[N{{H}_{4}}HS\left( s \right)\] is solid for solid active mass unity.
