We’re being asked to determine the time it would take for the 99% of the protein sample to decompose.
The integrated rate law for a first-order reaction is as follows:
[A]t = concentration at time t
k = rate constant
t = time
[A]0 = initial concentration.
The protein that you’ve just isolated is unstable; it decomposes through a first-order process with k = 0.02 min-1. How long will it take for 99% of a 1 mL sample of the protein, with initial concentration 87 μM, to decompose?
A. 0.05 sec
B. 0.5 min
C. 230 sec
D. 86 min
E. 3.8 hr
