Answer 2

Answer:

Time taken by the reaction to get complete can be determine by dividing initial concentration from rate constant of the reaction.

Explanation:

The integrated rate law for zero order kinetics is given as:

$[A]=[A_o]-kt$

[A] = concentration of substance left after time t

$[A_o]$ = initial concentration of the substance

k = rate constant of the reaction

If the initial concentration of the substance = a

Concentration after reaction gets completed = 0

$0=a-kt$

$t=\frac{a}{k}$

Time taken by the reaction to get complete can be determine by dividing initial concentration from rate constant of the reaction.
