Detailed Description

The 3-parameter SRI falloff function for F

The falloff function defines the value of \( F \) in the following rate expression

\[ k = k_{\infty} \left( \frac{P_r}{1 + P_r} \right) F \]

where

\[ P_r = \frac{k_0 [M]}{k_{\infty}} \]

\[ F = {\left( a \; exp(\frac{-b}{T}) + exp(\frac{-T}{c})\right)}^n \]

where

\[ n = \frac{1.0}{1.0 + {\log_{10} P_r}^2} \]

\( c \) s required to greater than or equal to zero. If it is zero, then the corresponding term is set to zero.
