Complete Chemistry For EATEA

absolute zero (0 K), the situation is special:

Classical view: In classical physics, gas molecules would have no kinetic energy at all. They would be completely at rest.

Quantum view: In quantum mechanics, even at absolute zero, molecules (or atoms) retain a minimum energy called zero-point energy.

This energy comes from the Heisenberg Uncertainty Principle: you cannot simultaneously have both exact zero momentum and exact position.

Therefore, molecules still possess some residual vibrational energy (for solids) or ground-state energy in their quantum states.

At absolute zero, gas molecules have zero-point energy (quantum mechanical energy that cannot be removed), but they have no thermal kinetic energy in the classical sense.

The correct increasing acidity order of the following Lewis acids is
AlF3> AlCl3 >AlBr3> AlI3.
Give the reason??
