"Okay, if I remember correctly, enthalpy is the change in heat plus any work done by the system." True: H = U + PV, where U is internal energy, P is pressure,...

I believe that Dr. J is tying to ask, Is there a way to predict the rate determining step? As far as I know, the answer is no. There are many factors that need...

I think my response got lost. The first step, the dissociation of the halogen into atomic halogen (i.e. X2 > 2X), is not the RDS. If it were, iodine would be...
