### Arrhenius Equation

I was wondering how the Arrhenius Equation would be changed algebraically with the given equation on the formula sheet to the one in the reader?

### Re: Arrhenius Equation

Hi!
I believe your equation actually works. I tried using the one you wrote and the one in the equation sheet and I got the same answer.
I think one of the problem is that you used the wrong T2 (temperature). It should be 350K not 348K because the second temperature is 77 degree Celsius not 75 degree Celsius. Also, when I use the Arrhenius Equation, I try not to round anything until the very end. When you use the natural log, small differences in the numbers can change your final answer.

### Re: Arrhenius Equation

I give a second confirmation, you can use that equation as well, and many of the PLF's teach the Arrhenius Equation this way, so like the first replier stated, it's not the fault of the equations.

Although, my TA did mention before we took the quiz, it's always more favorable to use the equations they give you on the sheet.
