Boniface Omar is on a distinguished road

Can someone please help me write a FLUENT UDF the reaction below which is defined by reaction rate equation of (R) below


R=k exp (E/RT)*(Pco^m*Ph2^n)

R is the volumetric reaction rate
k is Rate constant
E is Activation energy for reaction
R is Universal gas constant
T is Temperature
Pco is Partial pressure of carbon monoxide
Ph2 is Partial pressure of hydrogen
m is Power for CO partial pressure
n is Power for H2 partial pressure


Thank you.
