Cyclobutane Decomposes to Ethene in a First-Order Reaction

Question 67

Essay

Cyclobutane decomposes to ethene in a first-order reaction. From measurements of the rate constant (k) at various absolute temperatures (T), the accompanying Arrhenius plot was obtained (ln k versus 1/T). Cyclobutane decomposes to ethene in a first-order reaction. From measurements of the rate constant (k) at various absolute temperatures (T), the accompanying Arrhenius plot was obtained (ln k versus 1/T). a. Calculate the energy of activation, E<sub>a</sub>. b. Determine the value of the rate constant at 740. K. (In the plot, the units of k are s<sup>-1</sup>.) a. Calculate the energy of activation, Ea.
