Question
A reaction has a rate constant of 3.5 x 10-3 s-1. Calculate the half-life of this reaction. Please give your answer to the nearest second.
Solution
The half-life of a first-order reaction is calculated using the formula:
t1/2 = 0.693 / k
where: t1/2 is the half-life of the reaction, k is the rate constant of the reaction.
Substituting the given value of k into the formula, we get:
t1/2 = 0.693 / (3.5 x 10^-3 s^-1) = 198.0 seconds
So, the half-life of this reaction is approximately 198 seconds.
