If the half-life ($t_{1/2}$) for a first-order reaction is 1 minute, then the time required for 99.9% completion of the reaction is closest to:
If the half-life ($t_{1/2}$) for a first-order reaction is 1 minute, then the time required for 99.9% completion of the reaction is closest to:
Show Hint
For a first-order reaction, the time for 99.9\% completion can be calculated using the formula:
\[
t = \frac{\ln(1/0.001)}{k}
\]
Where \( k \) is determined from the half-life of the reaction.
