Question
The half life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99% of the chemical reaction will be (log 2 = 0.301) :
Options
A.230.3 minutes
B.23.03 minutes
C.46.06 minutes
D.460.6 minutes
Solution
∵ λ = 
min-1
Also t =
[Ao] = initial concentration (amount)
[A] = final concentration (amount)
∴ t =
= 46.06 minutes
min-1 Also t =
[Ao] = initial concentration (amount)
[A] = final concentration (amount)
∴ t =
= 46.06 minutes
