Question

question 5 (1 point)
which quantity does not increase when the temperature of a reaction system is raised?
activation energy
number of collisions
number of effective collisions
average kinetic energy of the particles
all of the above increase

Explanation:

Activation energy is a property of the reaction itself and is not affected by temperature. When temperature increases, particles move faster, leading to more collisions (number of collisions increases). More of these collisions have sufficient energy (average kinetic energy increases), so the number of effective collisions also increases.

Answer:

activation energy
