Statement I: Number of d and f electrons increases down the group and due to poor shielding of d and f electrons, stability of lower oxidation states increases down the group.
Statement II: The atomic size of aluminium is greater than that of gallium. Thus, Statement I is correct, but Statement II is incorrect.
For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \] Attainment of equilibrium is predicted correctly by:
