The rate constant (k) of a first-order reaction can be calculated using the formula:

k = 0.693 / t1/2

where:
k is the rate constant,
t1/2 is the half-life of the reaction.

Substituting the given value of t1/2 into the formula, we get:

k = 0.693 / 20 s
= 0.03465 s^-1

So, the rate constant for this reaction is approximately 0.035 s^-1 when rounded to three decimal places.
