I don't know the answer to long I just want points so plz like and thank me jk the answer is 12H2o
Answer : The time taken for the reaction is, 28 s.
Explanation :
Expression for rate law for first order kinetics is given by :
![k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA_o%5D%7D%7B%5BA%5D%7D)
where,
k = rate constant = 0.0632
t = time taken for the process = ?
= initial amount or concentration of the reactant = 1.28 M
= amount or concentration left time 't' = ![1.28\times \frac{17}{100}=0.2176M](https://tex.z-dn.net/?f=1.28%5Ctimes%20%5Cfrac%7B17%7D%7B100%7D%3D0.2176M)
Now put all the given values in above equation, we get:
![0.0632=\frac{2.303}{t}\log\frac{1.28}{0.2176}](https://tex.z-dn.net/?f=0.0632%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B1.28%7D%7B0.2176%7D)
![t=28s](https://tex.z-dn.net/?f=t%3D28s)
Therefore, the time taken for the reaction is, 28 s.
