Calculate the value of Delta S when 1.00 mole of ethanol is vaporized at 78.0°C and 1.00 atm.
I get 110 J/K mol, but is it a negative or positive number, I want to say because of vaporization it is an endothermic response which would make the number 110 J/K mol.© BrainMass Inc. brainmass.com March 4, 2021, 10:26 pm ad1c9bdddf
Hello and thank you for posting your question to Brainmass.
Yes, your reasoning is correct. Heat Q flows *into* the system thus it has a positive value.
Entropy change is the ratio between the heat amount and the ...
This solution helps with a problem about thermodynamics.
