What does “Half-life” actually mean in Chemical Kinetics, and why does it matter for JEE?
the time for a reactant to fall to half its amount; for first-order reactions it's constant.
In simple words: the time for a reactant to fall to half its amount; for first-order reactions it's constant. Getting Half-life clear matters because JEE questions on Chemical Kinetics usually test this idea directly, not just a formula you memorised.
Key point
Half-life
Common mistake
assuming half-life is constant for every order.
Memory tip
constant half-life is a signature of first-order kinetics.
