1. anonymous

A certain reaction has an activation energy of 60.0kj/mole and a frequency factor of = 4.30×1012. What is the rate constant,k , of this reaction at 30.0 ? help please

2. abb0t

Are you familiar with the Arrhenius equation? $k = Ae^{-\frac{ E_a }{ RT} }$

3. abb0t

Ea is activation energy, R is your constant, T is your temperature. A is your frequency factor.

yes i even plugged in the numbers but i didnt work

5. anonymous

maybe i put in the number wrongly

6. abb0t

Did you take into account the negative sign?

7. anonymous
