Question

Pure ammonia is placed in a vessel at a temperature where its dissociation constant `(alpha)` is appreciable. At equilibrium,
A. `K_(p)` does not change significantly with pressure
B. `alpha` does not change with pressure
C. concentration of `NH_(3)` does not cahange with pressure
D. concentration of hydrogen is less than that of nitrogen

Answer 1

Correct Answer - A
`K_(p)` depends only on temperature so `alpha` will change on changing pressure and `P_(H_(2)) gt P_(N_(2))` .
