Forward vs Reverse Reaction (both endo/exo thermic)
« on: April 09, 2011, 04:01:26 AM »
Can both the forward and reverse reaction be endothermic or exothermic?  Or must they ALWAYS be inverse each other?

Thanks

NO reaction can be both endothermic and exothermic. If the forward reaction is endothermic, the backward reaction HAS to be exothermic.

Thank you. That makes sense. I was curious if there are any special exceptions somehow.

Nope.  You should read up on the principle of microscopic reversibility.
