I am reading a book on microwave synthesis, where I saw the activation
energy for a 'middle of the range' organic reaction as 50 kcal/mol.
Is this a reasonable value? Or is 50 kJ/mol a more sensible number to work
with?
Another way to put it: What is the rule of thumb about how much faster a
reaction goes when you raise the temperature ten degrees (Or is it 20?).
I am trying to understand if there is any sound basis for talking about an
instantaneous temperature as being higher than the bulk temperature during a
microwave synthesis. It all looks a bit phoney to me..
yours,
Thomas Høyer
