Part A

We are being asked to determine the half-life of the following reaction

cyclopropene, C_{3}H_{6} (g) → propene, C_{3}H_{6} (g)

We will use the following formula to solve this problem

$\overline{){{\mathbf{t}}}_{\raisebox{1ex}{$\mathbf{1}$}\!\left/ \!\raisebox{-1ex}{$\mathbf{2}$}\right.}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{ln}\mathbf{}\mathbf{2}}{\mathbf{k}}}$

Consider the first-order reaction described by the equation cyclopropane propene

At a certain temperature, the rate constant for this reaction is 5.62x10^{-4} s^{-1}. Calculate the half-life of cyclopropane at this temperature.

Given an initial cyclopropane concentration of 0.00850 M, calculate the concentration of cyclopropane that remains after 2.20 hours.
