• Statement (D): The stability of the +5 oxidation state decreases down the group due to the inert pair effect.
• Statement (E): Nitrogen belongs to the second period and cannot expand its octet, hence it cannot show a maximum covalency of 6.
Corrected Statements: - +5 oxidation state stability decreases down the group. - Nitrogen shows a maximum covalency of 4.
For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \] Attainment of equilibrium is predicted correctly by:
