What does “Order of reaction” actually mean in Chemical Kinetics, and why does it matter for JEE?
the power to which a reactant's concentration is raised in the experimentally-determined rate law.
In simple words: the power to which a reactant's concentration is raised in the experimentally-determined rate law. Getting Order of reaction clear matters because JEE questions on Chemical Kinetics usually test this idea directly, not just a formula you memorised.
Key point
Order of reaction
Common mistake
reading the order off the balanced equation's coefficients.
Memory tip
order comes from experiment, not stoichiometry (unless the step is elementary).
