For a first order reaction, t_(1//2) = underset(k)ul(...........) .

The order of reaction is an experimentally determined quanity. It may be zero, poistive, negative, or fractional. The kinetic equation of nth order reaction is k xx t = (1)/((n-1))[(1)/((a-x)^(n-1)) - (1)/(a^(n-1))] …(i) Half life of nth order reaction depends on the initial concentration according to the following relation: t_(1//2) prop (1)/(a^(n-1)) ...(ii) The unit of the rate constant varies with the order but general relation for the unit of nth order reaction is Units of k = [(1)/(Conc)]^(n-1) xx "Time"^(-1) ...(iii) The differential rate law for nth order reaction may be given as: (dx)/(dt) = k[A]^(n) ...(iv) where A denotes the reactant. In a chemical reaction A rarr B , it is found that the rate of the reaction doubles when the concentration of A is increased four times. The order of the reaction with respect to A is:

For a reaction whose rate expression is rate (dx)/(dt)=k[A]^(1//2) [B]^(3//2) the overall order of the reaction will be:
