How to Calculate Reaction Rate
Compute differential rate law kinetics step-by-step:
STEP 01
Enter Rate Constant k
Input reaction rate constant value k.
STEP 02
Enter Reactant Concs
Input molar concentrations [A] and [B] in mol/L.
STEP 03
Specify Reaction Orders
Input reaction orders m and n (0, 1, 2, or 3).
STEP 04
Compute Rate (M/s)
Multiply Rate = k × [A]^m × [B]^n for reaction velocity in mol/(L·s).

Kinetics Guide: The Differential Rate Law
The Reaction Rate measures the change in reactant or product concentration per unit time:Rate = -d[A]/dt = k · [A]m · [B]n

Frequently Asked Questions
?Can reaction orders be zero?
Yes. For a zero-order reactant (order = 0), changing its concentration has zero effect on reaction speed ([A]⁰ = 1).
