The activation barrier for an uncatalyzed reaction is, Ask an Expert

Academics

The activation barrier for an uncatalyzed reaction is estimated to be 17 kcal/mol. The activation barrier for the catalyzed reaction is estimated to be 11.5 kcal/mol. How many times faster is the catalyzed rate versus the uncatalyzed rate? In other words, by what factor/coefficient do you have to multiply the uncatalyzed rate to equal the catalyzed rate? Assume the temperature is 298 K.
