A first order reaction is 75% completed in 1000 s at 300 K. What is its half-life period at 300 K?
Show Hint
Memorize these relationships for first-order reactions:
\(t_{75\%} = 2 \times t_{1/2}\)
\(t_{87.5\%} = 3 \times t_{1/2}\)
\(t_{99.9\%} \approx 10 \times t_{1/2}\)
\(t_{75\%} = 2 \times t_{1/2}\)
\(t_{87.5\%} = 3 \times t_{1/2}\)
\(t_{99.9\%} \approx 10 \times t_{1/2}\)
