You don't have any units on k. Also, I'm not sure I've translated the mumbo jumbo symbols you have correctly so check the below carefully.
ln(No/N) = kt
No = 100
N = 11.75
k = 6.7E-4 (min^-1 or sec^-1 or whatever)
t = time and the time will be minutes, seconds, hours, days, or whatever the unit of k. Then time will need to be convert to minutes if k is in some unit other than minutes.
The following rearrangement reaction is first order:
C3H6 �¨ CH3CH=CH2
The rate constant for this reaction is 6.7 �~ 10−4. How many minutes will it take for the concentration of C3H6 to drop to 11.75% of its initial value?
How do I calculate this step by step.
My answer was 3.1 minutes and it was wrong.
