23. What does Maxwell-Boltzmann distribution of molecular speeds inform? Volume of NaOH added (mL)
(A) Through collision with each other, all gas molecules reach the same speed at thermal equilibrium
(B) For the same molecule, its root mean square (r.m.s.) speed increases with increasing temperature
(C) At the same temperature, lighter molecules would have higher r.m.s. speed
(D)P（E）, the probability of a molecule possessing a certain kinetic energy E, always decreases with E
(E) Individual gas molecules do not have the same kinetic energy
