According to Maxwell , Boltzmann distriubtion of energy ……… .

Options

A. the fraction of moleucles with most probable kinetic enegy decreases at higher temperatures
B. the fraction of moleucles with most probable kinetic enegy increases at higher temperatures
C. most probable kinetic energy increases at higher temperature
D. most probable kinetic energy decreases at higher temperature

Answer

A, C

Explanation

Distributions of kinetic energy may be described by plotting a graph of fraction of molecules versus.

kinetic energy of maximum fraction of molecule is know as most probable kinetic energy. It is important to note that with increase of temperature, peak shifts forward but downward.
This means that with increase of temperature,
(i) most probable kinetic energy increases.
(ii) the fractions of molecules possessing most probable kinetic energy decreases.
