In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
However it is not always true that the rate of a reaction increases with increase in temperature. Certain reactions like biological reactions which are catalyzed by enzymes may be slowed down with increase in temperature since the enzymes may lose their activity (see below for more explanation about a catalyst).
