Question 1

The figure represents the spontaneous evaporation of nitrogen in which liquid nitrogen, N2(l), becomes gaseous nitrogen, N2(g): N2(l) → N2(g). What are the signs (+ or -) of ΔH, ΔS, and ΔG for this process?



◦ ΔH = +, ΔS = +, ΔG = +
◦ ΔH = -, ΔS = -, ΔG = +
◦ ΔH = -, ΔS = -, ΔG = -
◦ ΔH = +, ΔS = +, ΔG = -

Question 2

An ideal gas is expanded at constant temperature. What are the signs (+, -, or 0) of ΔH, ΔS, and ΔG for this system?



◦ ΔH = 0, ΔS = +, ΔG = -
◦ ΔH = -, ΔS = +, ΔG = -
◦ ΔH = 0, ΔS = -, ΔG = +
◦ ΔH = +, ΔS = -, ΔG = +
