nth Order Kinetics

The rates of the reaction is proportional to nth power of reactant

Differential rate law

\mathrm{=\frac{dx}{dt}=k(a-x)^{n}}

Integrated rate laws,

\mathrm{=\frac{1}{n-1}[(a-x)^{1-n} -a^{(1-n)}]=k_nt}

a= initial, concentration of reactant at t=0 sec

x= concentration of product formed at t= tsec

\mathrm{t_\frac{1}{2}=\frac{1}{(n-1)(a^{n-1})(k_n)}[2^{n-1}-1]}
