Increase in rate of reaction with rise in temperature is mainly due to increase in collision frequency/effective collisions.

Why does the rate of a reaction increase with rise in temperature?

According to collision theory of chemical reactions, rate of a reaction depends upon collision frequency and fraction of effective collisions. The rate of a reaction generally increases with rise in temperature mainly because of increase in number of effective collisions. Arrhenius proposed a quantitative relation between rate constant and temperature as k= Ae^(-E_a//Rt) where E_a is activation energy. It is equal to the difference between threshold energy and average kinetic energy of reacting molecules. Which of the following plot will be linear ?
