The activation energy for a reaction is changed from 184 kj/mol to 60.5 kj/mol at 600. k by the introduction of a catalyst. if the uncatalyzed reaction takes about 2537 years to occur, about how long will the catalyzed reaction take? assume the frequency factor a is constant and assume the initial concentrations are the same.

The catalyzed reaction will take 1,41 s

Explanation:

The rate constant for a reaction is:

Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:

Replacing:

That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:

4,50x10⁻⁸ years××× = 1,41 s

I hope it helps!

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.
