Pre-exponential factor A
« on: March 03, 2009, 09:04:56 AM »
Hi everyone!

I was kinda wondering... what are pre exponential factors? Do i get a direct literature value for this?
I have some difficulty answering my chemistry problem because i need a value for A.

The reaction is:

NH4NO3 + H2O(l)  :rarrow: N2O + H2O(v)

thanks a lot in advance...  ;D

You could check the definition of pre-exponential factor online. Do you have any source to get value of A for your reaction? If no, what is your full question? Usually it could be determine via arrhenius plot.
