The formula to calculate the Half Life Period of a First Order Reaction is:
\[ t_{0.5} = \frac{\ln(2)}{K_h} \]
The Half Life Period is the time required for 50 percent completion of a first-order reaction. The Rate Constant is the coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of reactant or product.
Let's assume the following value:
Using the formula:
\[ t_{0.5} = \frac{\ln(2)}{1E-06} = 693147.180559945 \text{ Second} \]
The Half Life Period of the First Order Reaction is 693147.180559945 Second.
