hi,

i don't see this as a chemical reaction.  i see it as a physical change in state.  assuming temperature and pressure remain constant, the rate of change of solid into gas would remain constant and thus a '0' order operation.

Technetters,
It has been almost 30 years since I took kinetics.  I have dug out my old text books, but they only help so much. I'm a preparative inorganic chemist by training. My question is the following:  If a single compound sublimes, without decomposition, would you expect the kinetics to be zero or first order?  Thanks.
