Assertion: In Maxwell— Boltzmann distribution of speeds, the curve broadens at higher temperature. Reason: At a particular temperature, the individual speed of molecules as well as the distribution of speeds remains the same.

Speed distribution curve broadens at higher temperature because number of molecules moving at higher speed increases. At a particular temperature, the individual speed of molecules keeps changing but the distribution of speeds remains same.
