$16\mathrm{.}79$ For the unimolecular isomerization of cyclopropane to

propylene, values of $k_{\text{u}\text{n}\text{i}}$ versus initial pressure $P_0$ at $470C$ are

Take the reciprocal of Eq$.(16\mathrm{.}85)$ and plot these data in a way

that gives a straight line. From the slope and intercept, evaluate

$k_{\text{u}\text{n}\text{i}\text{,}P}=$ and the Lindemann parameters $k_1$ and $\frac{k_{-1}}{k_2}.$

Note: $k_{\text{u}\text{n}\text{i}}$ is defined by $r=k_{\text{u}\text{n}\text{i}}[A]$

$k_{\text{u}\text{n}\text{i}}=\frac{k_1{k}_2[M]}{k_{-1}[M]+k_2}=\frac{k_1{k}_2}{k_{-1}+\frac{k_2}{M}}$
