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 V 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 processes, 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.

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