Why does an increase in reaction temperature generally increase the reaction rate?

Increasing reaction temperature increased the kinetic energy in the system. In fact, the measurement of temperature indirectly relates the relative amount of kinetic energy in a system.
An increase in kinetic energy results in more rapid and forceful molecular collisions, thereby increasing the rate of molecular interactions (and in a fixed-volume system, the pressure increases as well!). Hence, the reaction can occur more quickly.
