Question

Write
(i) Arrhenius equation.
(ii) The formula to calculate the half-life period of zero order reaction.

Answer 1

(i) Arrhenius equation is $k=A{e}^{-Ea/RT}$ or $lnk=lnA-\frac{E_a}{RT}$. Here, k is the rate constant, A is the preexponential factor, Ea is the energy of activation, R is the ideal gas constant and T is absolute temperature.
(ii) The formula to calculate half life period $t_{1_{/2}}$of zero order reaction is $t_{1_{/2}}=\frac{[R{]}_o}{2k}$. Here, k is the rate constant and $[R{]}_o$ is the initial concentration of reactant.
