Answer:

0.3 s.

Explanation:

Half-life of a first order reaction is defined as the the time taken for any fraction of the reaction to complete is independent of the initial concentration.

Half-life of a first order reaction, t° = 0.693/k

where,

t° = half-life of the reaction

k = rate constant

= 2.3 s^-1

Therefore,

t° = 0.693/2.3

= 0.30 s.
