hi there bestie [i think its 3]
Solids have least energetic molecules because they are tightly packed.
This is late but for anyone else who needs it...It's D. Far left
Answer:
For example, the atomic radius of the metal zirconium, Zr, (a period-5 transition element) is 155 pm (empirical value) and that of hafnium, Hf, (the corresponding period-6 element) is 159 pm. ... The increase in mass and the unchanged radii lead to a steep increase in density from 6.51 to 13.35 g/cm3.

Answer:
A, B and D
Explanation:
The rate determining step decides the overall rate of reaction and the species involved in the rate determining step determine the overall order of reaction. All the elementary steps in the mechanism sum up to give the overall reaction equation. However, transient intermediates only appear in elementary reaction equations and not the overall reaction equation.
