The Arrhenius equation for the dependence of the rate constant, k, on temperature is given by In k = + In A, where A is the frequency factor, R is the ideal gas constant, and EA is the activation energy. The rate of conversion of cyclo-propane to propene in gas phase was measured over the temperature range 750-900 K, and the rate constants that were found are reported below. Hint: think about what the following equation means In = (1,...

The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k=Ae−Ea/RT where R is the gas constant (8.314 J/mol⋅K), A is a constant called the frequency factor, and Ea is the activation energy for the reaction. However, a more practical form of this equation is lnk2k1=EaR(1T1−1T2) which is mathmatically equivalent to lnk1k2=EaR(1T2−1T1) where k1 and k2 are the rate constants for a single reaction at two different absolute...
