1.	Pure ammonia is placed in a vessel at a temperature where its degree of dissociation (alpha) is appreciable. At equilibrium 2NH_(3) = N_(2) + 3H_(2) .
Answer» `K_p` does not change with PRESSURE `ALPHA` changes with pressure concentration of `NH_3` does not change with pressure concentration of `H_2` is more than that of `N_2` Solution :Le-chatelier.s principle
