As discussed before, the t1/2 of a zero order reaction is given as
while for the first order reaction it is given as
In general, for a reaction of order n, t1/2 is proportional to initial concentration of A raised to power n - 1, that is,
Only for the first order reaction t1/2 is independent of the initial concentration of the reactant. This relation can be used to determine the order of a reaction.
