Question
Is activation energy dependent on temperature?
Open in App
Solution
Yes, a
ctivation energy depends on the temperature.
It is the amount of energy required to activate a molecule for proceeding in a particular reaction.
With the increase in temperature, molecules start moving at a higher speed because of the gain in energy (kinetic energy).
With the increase in temperature the collision of particles increases, and the reaction takes place.
