The temperature dependence of the first-order rate constant is: T(K) . . . . k(s^-1)

1.) Calculate the activation energy, in kJ/mol. Use all data points and do a linear regression using calculator or Excel. Do not pick 2 data points. This is less accurate and assumes all data points are equally good.

2.) Calculate the frequency factor A (in s ^-1).

3.)

The activation energy for the isomerization of cyclopropane to propene is 274 kJ/mol. By what factor does the rate of this reaction increase as the temperature rises from 257 to 292 ^oC? (The factor is the ratio of the rates.)
