+Note: The pre-exponential values are determined using a surface site density of 2.72E-5 mol/m2 (same as in the Deutschmann 2006 mechanism). 
+The pre-exponenitals listed here are calculated as follows: A = A_from_paper/(surface site density)^(n-1)*(300K)^b), where n is the
 order of reaction and b is the given temperature exponent. 
 For sticking coefficients, A = sticking_coefficient_from_paper/(300K)^b.
 The activation energy is for 300K and does not include coverage or temperature dependence terms.
