# Problem: Cyclopropane rearranges to form propene in the gas phase.The reaction is first order in cyclopropane and has a measured rate constant of 3.36 x 10-5 s-1 at 720 K. If the initial cyclopropane concentration is 0.0505 M, what is the cyclopropane concentration after 251 minutes?

###### FREE Expert Solution

We are asked to determine the amount of the cyclopropane concentration after 251 minutes

The integrated rate law for a 1st-order reaction is as follows:

where rate= rate at time t, k = rate constant, t = time, initial rate = starting rate
