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,E_a.
b.Determine the value of the rate constant at 740.K.(In the plot,the units of k are s^-1. )
