Ratio of Pre Exponential Factor - Ratio of pre exponential factor is the ratio of the collision diameter and reduced mass of one reaction with collision diameter and reduced mass of the second reaction.
Collision Diameter 1 - (Measured in Meter) - Collision Diameter 1 is defined as the distance between the centers of two colliding molecules when at their closest point of approach in reaction 1.
Reduced Mass 2 - (Measured in Kilogram Per Mole) - Reduced Mass 2 is defined as the mass that is taken after colliding the two molecules which is equal to the quotient of the product of the two masses divided by their sum in reaction 2.
Collision Diameter 2 - (Measured in Meter) - Collision Diameter 2 is defined as the distance between the centers of two colliding molecules when at their closest point of approach in reaction 2.
Reduced Mass 1 - (Measured in Kilogram Per Mole) - Reduced Mass 1 is defined as the mass that is taken after colliding the two molecules which is equal to the quotient of the product of the two masses divided by their sum in reaction 1.
STEP 1: Convert Input(s) to Base Unit
Collision Diameter 1: 4 Meter --> 4 Meter No Conversion Required
Reduced Mass 2: 4 Gram Per Mole --> 0.004 Kilogram Per Mole (Check conversion here)
Collision Diameter 2: 3 Meter --> 3 Meter No Conversion Required
Reduced Mass 1: 6 Gram Per Mole --> 0.006 Kilogram Per Mole (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A1/A2 = (((D1)^2)*(sqrt(μ 2)))/(((D2)^2)*(sqrt(μ 1))) --> (((4)^2)*(sqrt(0.004)))/(((3)^2)*(sqrt(0.006)))
Evaluating ... ...

## What is Pre Exponential Factor ?

The pre-exponential factor is also known as the frequency factor and represents the frequency of collisions between reactant molecules at a standard concentration. Although often described as temperature-independent, it is actually dependent on temperature because it is related to molecular collision, which is a function of temperature.
