Question
An atomic isotope radioactively decays and has a half-life of 23.7 days. How many days will it take for 88.2% of the sample to decay?
In([A]MA]) = -kt
t1/2 = (In2/k)
券
(1/[A]) = kt + (1/AI,)
t1/2 (1/k[A],)
[A]=-kt + [Alo
t1/2 = ([A]/2k)
In(k2/kq) = (E/R)[(1/T;)- (1/T2)]
R= 0.0820573L atm/(K mol)
उस
R = 8.31446 J 7(K mol)
Type your answer in the space below without the units.
