Q4. A reaction, A + B → C + D + q is found to have a positive entropy change. The reaction will be
Answer : Option C
Explaination / Solution:
ΔG = ΔH -T ΔS
ΔS is positive and ΔH is negative as heat is liberated in the reaction.
so ΔG is negative hence reaction will be spontaneous at all temperature.

Q9. The outer electronic configuration of f - Block elements are:
Answer : Option C
Explaination / Solution:
The two rows of elements at the bottom of the Periodic Table, called the Lanthanoids, Ce(Z = 58) – Lu(Z = 71) and Actinoids, Th(Z = 90) – Lr (Z = 103) are characterised by the outer electronic configuration (n-2)f1-14 (n-1)d0-1ns2. The last electron added to each element is filled in f- orbital.
