Does frequency factor change with temperature
Did you know?
WebSo we can say that Frequency is directly proportional to the square root of temperature. So, on increasing the temperature, the collision frequency increases and hence, the fraction of effective collisions increases, so these collisions lead to and increase in the energy of the reactants.
