  In the graph showing Maxwell, Boltzmann distribution of energy......... (a) area under the curve must not change with 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 increase in temperature curve broadens and shifts to the right hand side

Answer:

                  (a, d) According to Maxwell Boltzmann distribution curve, area under the curve must not change with increase in temperature. But with increase in temperature curve broadens and shift 'towards right hand side due to decrease in fraction of molecules having most probable kinetic energy.
