Question

a first order reaction is found to have a rate constant, K=5.5*10^-14 s^-1.
find the half life of the reaction.

Answer 1

half life is 0.126×10¹⁴ s

Answer 2

T (half)= 0.693/ k

K is give in the question

Therefore T (half)= 0.693/(5.5*10^-14)

= 1.26*10^13 seconds

I guess I am correct
