Increasing the temperature, as noted in the graph, increases the rate of this chemical reaction. What is the relationship betwee
n 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.
Answer: (C) Although the average kinetic energy of the colliding substances increases, this has no influence on activation energy.
Explanation:
After increasing the temperature of the reaction , the rate of the chemical reaction increases due to increase in the average kinetic energy of the particles. At increased temperature high proportions of particles can react making the reaction faster.
