How to Calculate and Solve for Rate Constant | Mineral Processing
Last Updated on December 9, 2021
The image above represents rate constant.
To compute for 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
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
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 is Given.
Ka = K x Kd
Where:
Ka = Absorption Proportionality Constant
K = Rate Constant
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
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 is Given.
Kd = Ka / K
Where:
Kd = Desorption Proportionality Constant
K = Rate Constant
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
Kd = Ka / K
Kd = 48 / 12
Kd = 4
Therefore, the desorption proportionality constant is 4.
