Increasing the temperature, as noted in the graph, increases the rate of this chemical reaction. what is the relationship between increased temperature and activation energy in a typical chemical reaction? a) as the kinetic energy of the substances increases, the overall activation energy also increases. b) the proportion of collisions that can overcome the activation energy for the reaction increases with temperature. c) although the average kinetic energy of the colliding substances increases, this has no influence on activation energy. d) the proportion of collisions that can overcome the activation energy for the reaction decreases as temperature increases.
