Explanation:
<u>Answer:</u> The half life of cyclopropane at 760 K is 28.99 minutes.
<u>Explanation:</u>
Rate law expression for first order kinetics is given by the equation:
![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 = ?
t = time taken for decay process = 6.8 minutes
= initial amount of the sample = 100 grams
[A] = amount left after decay process = (100 - 15) = 85 grams
Putting values in above equation, we get:

The equation used to calculate rate constant from given half life for first order kinetics:

where,
= half life of the reaction = ?
k = rate constant of the reaction = 
Putting values in above equation, we get:

Hence, the half life of cyclopropane at 760 K is 28.99 minutes.
