Answer:
The catalyzed reaction will take 2.85 seconds to occur.
Explanation:
The activation energy of a reaction is given by:
![k = Ae^{-\frac{E_{a}}{RT}}](https://tex.z-dn.net/?f=%20k%20%3D%20Ae%5E%7B-%5Cfrac%7BE_%7Ba%7D%7D%7BRT%7D%7D%20)
For the reaction without catalyst we have:
(1)
And for the reaction with the catalyst:
(2)
Assuming that frequency factor (A) and the temperature (T) are constant, by dividing equation (1) with equation (2) we have:
![\frac{k_{1}}{k_{2}} = \frac{Ae^{-\frac{E_{a_{1}}}{RT}}}{Ae^{-\frac{E_{a_{2}}}{RT}}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bk_%7B1%7D%7D%7Bk_%7B2%7D%7D%20%3D%20%5Cfrac%7BAe%5E%7B-%5Cfrac%7BE_%7Ba_%7B1%7D%7D%7D%7BRT%7D%7D%7D%7BAe%5E%7B-%5Cfrac%7BE_%7Ba_%7B2%7D%7D%7D%7BRT%7D%7D%7D%20)
Since the reaction rate is related to the time as follow:
![k = \frac{\Delta [R]}{t}](https://tex.z-dn.net/?f=%20k%20%3D%20%5Cfrac%7B%5CDelta%20%5BR%5D%7D%7Bt%7D%20)
And assuming that the initial concentrations ([R]) are the same, we have:
![\frac{k_{1}}{k_{2}} = \frac{\Delta [R]/t_{1}}{\Delta [R]/t_{2}}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bk_%7B1%7D%7D%7Bk_%7B2%7D%7D%20%3D%20%5Cfrac%7B%5CDelta%20%5BR%5D%2Ft_%7B1%7D%7D%7B%5CDelta%20%5BR%5D%2Ft_%7B2%7D%7D%20)
![\frac{k_{1}}{k_{2}} = \frac{t_{2}}{t_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7Bk_%7B1%7D%7D%7Bk_%7B2%7D%7D%20%3D%20%5Cfrac%7Bt_%7B2%7D%7D%7Bt_%7B1%7D%7D)
![t_{2} = t_{1}\frac{k_{1}}{k_{2}} = 6900 y*1.31 \cdot 10^{-11} = 9.04 \cdot 10^{-8} y*\frac{365 d}{1 y}*\frac{24 h}{1 d}*\frac{3600 s}{1 h} = 2.85 s](https://tex.z-dn.net/?f=%20t_%7B2%7D%20%3D%20t_%7B1%7D%5Cfrac%7Bk_%7B1%7D%7D%7Bk_%7B2%7D%7D%20%3D%206900%20y%2A1.31%20%5Ccdot%2010%5E%7B-11%7D%20%3D%209.04%20%5Ccdot%2010%5E%7B-8%7D%20y%2A%5Cfrac%7B365%20d%7D%7B1%20y%7D%2A%5Cfrac%7B24%20h%7D%7B1%20d%7D%2A%5Cfrac%7B3600%20s%7D%7B1%20h%7D%20%3D%202.85%20s%20)
Therefore, the catalyzed reaction will take 2.85 seconds to occur.
