Hi, I'm an italian student in medicine, firts year. Today I had an examination on chemistry, and a question was:
Is better to have the reaction
CaCO3 --> CaO + CO2
in a close recipient or in a open recipient/space?
I answered in a close recipient, because of Le Chatelier principle, the temperature neeeded, and because in a close system you can actually remove the CO2, eliminating the problem of the CO2 pressure, but some other people answered differently, in open recipient, because of the CO2 pressure. The tutors who will correct the examination told someone the open recipient was the correct answer, but they were doubtfull too.
I'm on my way, I think mine is correct.
Sorry for my english and for the question if under your forum level, ...
Thank you for paying attention
If anyone will give me a reply...
Thank you very much!
