Apply: factors affecting reaction rates


Temperature is a measure of the average kinetic energy of a system. The diagram below shows a single chemical reaction at two different temperatures, T1 and T2. The relative number of molecular collisions is represented by the y-axis, and kinetic energy is on the x-axis. The activation energy (Ea) is represented by a dashed line.
At which temperature would the reaction likely proceed at a higher rate, and why?
