Question 1

The figure below represents the spontaneous reaction of H2 (shaded spheres) with O2 (unshaded spheres) to produce gaseous H2O.

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 below represents the spontaneous reaction of H2 (shaded spheres) with O2 (unshaded spheres) to produce gaseous H2O.

How will the spontaneity of this reaction vary with temperature? This reaction is
◦ nonspontaneous at all temperatures.
◦ nonspontaneous at high temperatures and spontaneous at low temperatures.
◦ spontaneous at all temperatures.
◦ spontaneous at high temperatures and nonspontaneous at low temperatures.
