MCQ
Pure ammonia is placed in a vessel at a temperature where its dissociation constant ($\alpha$) is appreciable. At equilibrium 
  • $K_p$ does not change significantly with pressure.
  • B
    $\alpha$ does not change with pressure.
  • C
    concentration of $NH_3$ does not change with pressure.
  • D
    concentration of hydrogen is less than that of nitrogen

Answer

Correct option: A.
$K_p$ does not change significantly with pressure.
a
$K_P$ depends only on temperature and mode of representation so $\alpha$ will change on changing pressure and ${P_{{H_2}}} > {P_{{N_2}}}$.
