About Reaction Kinetics

Reaction kinetics studies the rates of chemical reactions and the factors that influence them. The rate of a reaction depends on the concentrations of reactants, temperature, and the presence of catalysts. The reaction order determines how concentration changes affect the reaction rate.

•Features

–Calculate rate constants from experimental data
–Determine reaction half-lives
–Predict concentration changes over time
–Support for zero, first, and second-order reactions

•How to Use

1.Select the calculation type
2.Choose the reaction order
3.Enter the required values
4.Click calculate to get results

•Key Concepts

–Zero Order: Rate independent of concentration
–First Order: Rate proportional to concentration
–Second Order: Rate proportional to concentration squared
–Half-Life: Time for concentration to halve

•Formulas Used

Zero Order:

[A] = [A]₀ - kt
t₁/₂ = [A]₀/2k

First Order:

ln[A] = ln[A]₀ - kt
t₁/₂ = ln(2)/k

Second Order:

1/[A] = 1/[A]₀ + kt
t₁/₂ = 1/k[A]₀
