Cyclobutane Decomposes to Ethene in a First-Order Reaction

Question 6

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).
a.Calculate the energy of activation,Ea.
b.Determine the value of the rate constant at 740.K.(In the plot,the units of k are s-1. ) 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>. )
