In the graph showing Maxwell, Boltzmann distribution of energy ........ .
(a) area under the curve must not change with an increase in temperature
(b) area under the curve increases with increase in temperature
(c) area under the curve decreases with increase in temperature
(d) with an increase in temperature, curve broadens and shifts to the right-hand side
Answers: (a) and (d).
According to the Maxwell Boltzmann distribution curve, the area under the curve must not change with an increase in temperature. But with an increase in temperature curve broadens and shift towards right-hand side due to a decrease in the fraction of molecules having most probable kinetic energy.
