Reaction Order Calculator
Determine reaction order from concentration and rate data. Calculate rate constants and integrated rate laws.
Experimental Data
Method of Initial Rates:
The order is calculated by comparing how the rate changes when concentration changes:
n = log(r2/r1) / log(c2/c1)

About Reaction Order
Reaction order describes how the rate of a chemical reaction depends on the concentration of reactants. Zero-order reactions have constant rates, first-order rates are proportional to concentration, and second-order rates depend on concentration squared. Determining reaction order is essential for understanding reaction mechanisms and predicting how reactions behave.
