Answer»


Solution :(A)For isoelectronic species, the ionic size decrease with INCREASE in NUCLEAR charge
(B)Number of atomic shells increases, ionic size increases.
(C )Correct order,as Cl has less inter electronic repulsions than F due to bigger size of 3p-subshell
(D)Oxidation STATE increases, the electronegativity increases.For isoelectronic species IONISATION energy and electron affinity increases with increasing nuclear charge.

Solution :The CORRECT match is
`II rarr A, V rarr B, III rarr C, I rarr D`.
Their explanations are as follows :
`(D) rarr I`
In an isothermal reversible EXPANSION
`DELTA T = 0`
`Delta U = C_(V) , Delta T = 0`
`(A) rarr II`
If wall is adiabatic then
`q = 0`
From first law of thermodynamics
`Delta U = q + W`
`:. Delta U = W_("adiabatic")`
`(C ) rarr III`
For thermally conducting walls
`Delta U = -q`
`(B) rarr V`
For close system
`q != 0, w != 0` and `W = -ve`
From first law of thermodynamics
`Delta U = q - W`
