Quick answer
Select the integrated rate-law order. The half-life is order-specific: C0/(2k) for zero order, ln2/k for first order, and 1/(kC0) for second order.
Formula and steps
0th: C=C0−kt; 1st: C=C0e^(−kt); 2nd: C=1/(1/C0+kt)
Normalize the inputs first, keep working precision through intermediate steps, and round only the displayed result. Use the Reaction Kinetics when the next step requires a different chemistry model.
Assumptions and limits
This is a transparent planning model with a defined scope. It does not validate an instrument, sample identity, chemical safety, purity, or a regulated procedure.
Frequently asked questions
What does this kinetics order assume?
The assumptions shown above are part of the result. If your system falls outside them, select a more complete method rather than forcing the number.
How should I report the answer?
Keep the units, input basis, significant figures, and model limitations with the result.
