The isomerization of cyclopropane to for...

The isomerization of cyclopropane to form propane is a first order reaction. At `760 K, 85%` of a sample of cyclopropane change to propane in `79 min`. Calculate the value of the rate constant.

A

`A. 3.66 xx 10^(-2) min^(-1)`

B

`B. 1.04 xx 10^(-2) min^(-1)`

C

`C. 2.42 min^(-1)`

D

`D. 2.40 xx 10^(-2) min^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`:. k = (2.3)/(79 min) log.((100)/(100-85))`
Solve for `k ~~ 2.40 xx 10^(-2) min^(-1)`
