Essential Chemistry for IGCSE - Rate Of Reaction (Section 1 - No. 21)
Why does increasing the temperature increase the rate of reaction?
It increases the frequency of collisions between particles.
It decreases the activation energy.
It increases the kinetic energy of the reactant particles.
Both 1 and 3
Explanation
Increased temperature leads to more frequent collisions and particles with sufficient energy to overcome the activation barrier.
