### 15.69

Hi!

For problem 15.69, I was wondering if the rate coefficient was indicative of the rate? because I notice that in the solutions manual, even though the reaction rate increase by a factor of 1000., it uses the Arrhenius Equation and comparison of rate constants instead of reaction rates to get the answer

rate = k[reactant concentrations] so if k increases by a factor of 1000, the rate would also increase by a factor of 1000

In the equation, rate=K[reactants], K is directly related to the rate. Keep in mind, however, that K depends ONLY on the reaction and the temperature and will not change if the reactant concentrations change.
