Question 1

The figure above represents the nonspontaneous reaction O2(g) → 2O(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

The figure above represents the reaction O2(g) → 2O(g), which is nonspontaneous at 25°C. How will the spontaneity of this reaction vary with temperature? This reaction is
◦ spontaneous at high temperatures and nonspontaneous at low temperatures.
◦ nonspontaneous at all temperatures.
◦ spontaneous at all temperatures.
◦ nonspontaneous at high temperatures and spontaneous at low temperatures.
