Sorry for asking two questions in the same day. I admit, I have something due Monday, and I'm...you know...sort of panicking.
Anyway, the question.
"Starting from the reaction
C2H5OH + 3O2 -> 2CO2 + 3H2O
Find the heat and entropy change of the reaction when this reaction occurs at STP."
Okay, I know how to get entropy change (well, at least I know an equation:
q=Specific Heat x Change In Temperature x Mass
And I know that the STP that needs to be used is 22.4 L/mol. However, I'm not sure how to get the heat, and I'm not sure how to use the entropy equation that I presented if there's not even a change in temperature listed.
Help would be appreciated.
