Hi Alan,

 

Thanks once again. When i wanted to calculate Kg and kgprime values explicitly on function f3 and f5 i am not sure where my definition is wrong.

 

any suggestions.

 

thanks

I see - further down the worksheet than I was looking!

 

You have several terms that have an exponential with a unitless number divided by a temperature in K.  You need to make the ratio unitless by making the other numbers have units of K (or, equivalently, make the temperature unitless by dividing by K).

 

You define k.g but then try to use k.G in your definition of h.  If you make this k.g you have another error, namely M.MEA doesn't exist; you probably want M[MEA (i.e. true subscript, not a cosmetic one).  Correcting this, gives a further error, because it thinks T in the call to fCpgas is Teslas!  Make h a function of T to avoid this.

 

Alan
