Entropy vs. moles

Postby Shanzey » Sat Feb 08, 2020 11:41 pm

Does having more moles of a molecule mean increased entropy? For instance, would 5 moles of H2O would have a higher entropy compared to 1 mole of H2O?

I think in terms of a chemical equation, if you have a decrease in moles of the product, then entropy decreases and an increase in the moles of the product results in an increase in entropy

Yes, because there are more possible states and arrangements of the 5 moles of H2O compared to 2 moles H2O.

Yes, if you add matter to a system, the entropy will increase. More moles means more molecules which means more microstates for the molecules to be in.
