Final answer:
The half-life of the reaction is 21.6 minutes.
Step-by-step explanation:
The half-life of a first-order reaction can be calculated using the formula:
t1/2 = ln(2) / k
where t1/2 is the half-life, ln(2) is the natural logarithm of 2, and k is the rate constant. In this case, the rate constant is 5.36 x 10-4 s-1. Substituting this value into the formula:
t1/2 = ln(2) / (5.36 x 10-4)
t1/2 = 1293.9 s
Converting seconds to minutes:
t1/2 = 1293.9 s * (1 min / 60 s)
t1/2 = 21.6 min
