Match list-I with list-II and choose the correct option.

Given below are two statements:


Statement (II): Structure III is most stable, as the orbitals having the lone pairs are axial, where the $ \ell p - \beta p $ repulsion is minimum. In light of the above statements, choose the most appropriate answer from the options given below:

For 3 mol of an ideal gas \(\left[ C_{p,m} = \frac{5}{2}R \right]\), being heated from 300 K to 600 K, the change in entropy at constant pressure is
At 0 K, the molecule CO exists in two alternate arrangements (CO and OC) in the solid crystal. The value of the entropy is (where thermodynamic probability \( W = k^N \)):
