The image above represents rate constant. To calculate rate constant, two essential parameters are needed and these parameters are Absorption Proportionality Constant (Ka) and Desorption Proportionality Constant (Kd).
The formula for calculating rate constant:
K = Ka / Kd
Where:
K = Rate Constant
Ka = Absorption Proportionality Constant
And then, Kd = Desorption Proportionality Constant
Let’s solve an example;
Find the rate constant when the absorption proportionality constant is 6 and the desorption proportionality constant is 10.
This implies that;
Ka = Absorption Proportionality Constant = 6
Kd = Desorption Proportionality Constant = 10
That is, K = Ka / Kd
K = 6 / 10
K = 0.6
Therefore, the rate constant is 0.6.
Calculating the Absorption Proportionality Constant when the Rate Constant and the Desorption Proportionality Constant are Given
Ka = K x Kd
Where:
Ka = Absorption Proportionality Constant
K = Rate Constant
And then, Kd = Desorption Proportionality Constant
Let’s solve an example;
Find the absorption proportionality constant when the rate constant is 7 and the desorption proportionality constant is 3.
This implies that;

K = Rate Constant = 7
Kd = Desorption Proportionality Constant = 3
So, Ka = K x Kd
Ka = 7 x 3
Ka = 21
Therefore, the absorption proportionality constant is 21.

Calculating the Desorption Proportionality Constant when the Rate Constant and the Desorption Proportionality Constant are Given
Kd = Ka / K
Where:
Kd = Desorption Proportionality Constant
K = Rate Constant
And also, Ka = Absorption Proportionality Constant
Let’s solve an example;
Find the desorption proportionality constant when the rate constant is 12 and the absorption proportionality constant is 48.
This implies that;
K = Rate Constant = 12
Ka = Absorption Proportionality Constant = 48
Then, Kd = Ka / K
Kd = 48 / 12
Kd = 4
Therefore, the desorption proportionality constant is 4.
