Predict the sign of ΔS for each of the following systems,which occur at constant temperature
I.The volume of 2.0 moles of O₂(g) increases from 44 L to 52 L.
II.The pressure of 2.0 moles of O₂(g) increases from 1.0 atm to 1.2 atm.

Question

Quizplus · Accepted Answer

For I, the volume increase at constant temperature leads to an increase in entropy (ΔS = positive). For II, the pressure increase at constant temperature leads to a decrease in entropy (ΔS = negative).
