I have the same question here is proof:
Answer:
you can use the example of two magnets
Answer: 85 minutes
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
Half life for second order kinetics is given by:
= half life = 15 min
k = rate constant =?
= initial concentration = 100 (say)
![k=\frac{1}{1500}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7B1500%7D)
Integrated rate law for second order kinetics is given by:
![\frac{1}{a}=kt+\frac{1}{a_0}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Ba%7D%3Dkt%2B%5Cfrac%7B1%7D%7Ba_0%7D)
a= concentration left after time t = ![100-\farc{85}{100}\times 100=15](https://tex.z-dn.net/?f=100-%5Cfarc%7B85%7D%7B100%7D%5Ctimes%20100%3D15)
![\frac{1}{15}=\frac{1}{1500}\times t+\frac{1}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B15%7D%3D%5Cfrac%7B1%7D%7B1500%7D%5Ctimes%20t%2B%5Cfrac%7B1%7D%7B100%7D)
![t=85min](https://tex.z-dn.net/?f=t%3D85min)
Thus after 85 minutes after the start of the reaction, it will be 85% complete.
