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

Answer»

the fraction of MOLECULES with most probable kinetic energy DECREASES at higher tempreratures.
the fration of molecules with most probable kinetic energy increases at higher temperatures.
Most probable kinetic energy increases at higher temperatures
most probable kinetic energy decreases at higher temperatures

Solution :
From the GRAPH it is clear,
(A)As the TEMPERATURE increases the fraction of molecule at given kinetic energy decreases and height of graph decreases.
(D)As the temperature increases the graph shift towards right SIDE and kinetic energy increases.
