In General,as Temperature Increases,the Rate of a Chemical Reaction

In general,as temperature increases,the rate of a chemical reaction

A) decreases due to fewer collisions with proper molecular orientation.
B) increases for exothermic reactions,but decreases for endothermic reactions.
C) increases due to a greater number of effective collisions.
D) remains unchanged.
E) decreases due to an increase in the activation energy.
