Question 1

What is the entropy change associated with the expansion of one mole of an ideal gas from an initial volume of V to a final volume of 2.50V at constant temperature?
◦ ΔS = 2.50 R ln (Vf/Vi)
◦ ΔS = R ln 2.50
◦ ΔS = -2.50 R ln (Vf/Vi)
◦ ΔS = -R ln 2.50

Question 2

Predict the sign of ΔS for each of the following systems, which occur at constant temperature.
I.The volume of 2.0 moles of Ne (g) increases from 54 L to 62 L.
II.The pressure of 2.0 moles of Ne (g) increases from 0.90 atm to 1.0 atm.

◦ I: ΔS = positive; II: ΔS = positive
◦ I: ΔS = negative; II: ΔS = positive
◦ I: ΔS = positive; II: ΔS = negative
◦ I: ΔS = negative; II: ΔS = negative
