Kinetics Calculator (First-Order Half-Life)
🔬 What is a Kinetics Calculator?
A Kinetics Calculator helps you determine the half-life or other parameters of chemical reactions, especially in first-order reactions. It is useful for predicting how fast a reaction will occur and how long it takes for reactant concentrations to decrease.
⚖️ Formula (First-Order Half-Life)
The half-life of a first-order reaction is calculated using the formula:
t1/2 = 0.693 / k
where k is the rate constant of the reaction.
📘 Example
Suppose the rate constant (k) for a reaction is 0.002 s⁻¹.
Using the formula:
t1/2 = 0.693 / 0.002 = 346.5 seconds
This means it takes 346.5 seconds for the concentration of the reactant to decrease by half.
✅ Why Use It?
- Quickly calculate reaction half-life.
- Understand reaction speed and time required for completion.
- Useful for lab experiments and research studies.
