Most Important Selected Qs for JEE AdvancedChemistryChemical Equilibrium
The thermal dissociation equilibrium of NH ₄ HS ( s ) is studied under different conditions. NH ₄ HS ( ~s ) NH ₃( ~g )+ H ₂ ~S ( ~g ) For this equilibrium, the correct statement(s) is (are) :
Options
- AK depends on temperature
- BK is independent of the initial amount of NH ₄ HS (s)
- CK is dependent on the pressure of NH ₃ and H ₂ ~S at a given T
- DIf pressure of NH ₃( g ) is increased at equilibrium than pressure of H ₂ ~S ( g ) decreases at given temperat
Correct answer
D. If pressure of NH ₃( g ) is increased at equilibrium than pressure of H ₂ ~S ( g ) decreases at given temperat
Step-by-step solution
(A) Equilibrium constant depends on temperature. (B) Equilibrium constant is a constant. (C) P _ NH ₃ and P _ H ₂ ~S depend on K . (D) K = p _ NH ₃ p _ H ₂ ~S so if at equilibrium p _ NH ₃ is increased, then automatically p _ H ₂ ~S will decrease.
