Question

How temperature effect on reaction rate?

Answer 1

Increasing the temperature increasesreaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Answer 2

As temperature effects a lot in reaction.  It depends upon the reaction whether it is a exothermic or endothermic. Also due to temperature the product can also change
