How does a lone pair distort the molecular shape? O A. The lone pair forces bonding atoms farther from the nucleus.
B. The lone pair makes new bonds, changing the molecule's shape.
O C. The lone pair pushes bonding atoms closer to the nucleus.
O D. The lone pair forces bonding atoms away from itself.

D. The lone pair forces bonding atoms away from itself.

Explanation:

The lone pairs are found in the outermost shell thereby making sharing of electrons easier. Lone pairs which are found in a covalent bond creates a bond angle which makes it a determinant of the bond angle.

The lone pairs which are negatively charged repulses the bond pairs thereby creating a distortion in the shape of the molecule.

The lone pairs creates the distortion by forcing bonding atoms away from itself.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
