Three students are asked to discuss whether Gibbs Free Energy was positive or
negative for each dissolution. Select the student that employs correct
scientific reasoning.
. Student 1: The Gibbs Free Energy was negative for both reactions because the reactions were
spontaneous, the reactions happened.
• Student 2: The Gibbs Free Energy was positive for the first reaction because it got colder and
negative for the second reaction because it got hotter.
• Student 3: The Gibbs Free Energy was positive for both reactions because it is always positive for
dissolutions.
