Homework Help: Chemistry

Posted by Suriya on Sunday, February 27, 2011 at 11:36am.

Decomp. of H2O2 with Catalase.I am trying to use the Arrhenius equation in my coursework, but i am struggling to get it to work.
I have substituted most of the information in, such as activation energy(23000J), and gas constant(8.314x10-3) etc. The issue is "A" which is the pre exponential factor. im trying to work out a value for it, but i found i need to work out the rate constant. I got as far as working out initial rates of reaction for each of my temperatures i did my investigation with. I couldn't get an gurther, as my Hydrogen peroxide is in % concentration and my Catalase is in g/dm. I feel like im going around in circles, and i would really love some help, thankyou!
