Essential Chemistry for IGCSE - Rate Of Reaction (Section 1 - No. 43)
What is the relationship between the rate of reaction and the temperature, according to collision theory?
Increasing temperature increases the number of collisions, but decreases the effective collisions.
Increasing temperature increases both the number and the effectiveness of collisions.
Increasing temperature decreases the number of collisions, but increases the effectiveness of collisions.
Temperature has no effect on the number or effectiveness of collisions.
Explanation
Higher temperatures mean more kinetic energy, leading to more frequent and more effective collisions.
