Answer:
The catalyzed reaction will take 2.85 seconds to occur.
Explanation:
The activation energy of a reaction is given by:
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:
Since the reaction rate is related to the time as follow:
And assuming that the initial concentrations ([R]) are the same, we have:
Therefore, the catalyzed reaction will take 2.85 seconds to occur.
