For a reaction rate that increases by a factor of 655 in the presence of a catalyst at 37°C, the activation energy of the new pathway is mathematically given as

Ea2=89.28JKoule/mol

<h3>What is the activation energy of the new pathway, all other factors being equal?</h3>

Generally, the equation for the rate constant is mathematically given as

K=Ae^{Ea1/Rt}

Therefore

$\frac{1}{655}=\frac{1}{8.31*3.10}(Ea2-105000)$

Ea2=89286.083Joule/mol

In conclusion, the activation energy

Ea2=89.28JKoule/mol
