wall surface reaction. help
 

hello. If i define a wall surface reaction on a wall boundaries as :

h2o(l) ---> h2o (water wapor)

what values of "rate exponent" ( for reactants and products ) and " temperature exponent " should i use? please help thanks

Re: wall surface reaction. help
 

is this a reaction ? or just vaporization process?

is it possible to model vaporization process using surface reaction model?

It is a vaporization process, i'm tryng to model it with a reaction model on a surface of an object covered of water
