Hello

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

CO+3H2=>CH4+H2O

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

Where:
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.
