Boltzmann Distribution Curve:
a graph to show the distribution of energies of molecules at a particular temperature
T1 on the graph is at a lower temperature, the peak on this curve occurs at a lower energy and the area beneath the curve that is shaded is smaller.
T2 is at a higher temperature. The peak is lower but further along the energy axis. The area beneath this curve that is shaded is larger than that of T1 showing that more molecules have at least the activation energy and will react.
This graph shows why reactions will occur faster at a higher temperature.
