The kinetic energy of molecules in a system can be graphed as a distribution. When heat is added to the system,

more molecules have more energy, on average.

This is why kinetics depends on temperature so heavily, and reactions generally proceed at faster rates at higher temperatures.

More molecules are overcoming the activation energy #E_"a"# of the reaction.
