Question

A particular reactant decomposes with a half-life of 163 s when its initial concentration is 0.305 M. The same reactant decom

Answer 1

Answer #1

1)

From given data, we can see that as the concentration decreases half life increases.

This is true for 2nd order reaction

Answer: 2

2)

Given:

Half life = 163 s

use relation between rate constant and half life of 2nd order reaction

k = 1/([A]o*half life)

= 1/(0.305*1.63*10^2)

= 2.01*10^-2 M-1.s-1

Answer: 2.01*10^-2 M-1.s-1

Answer 2
