In Figure (1)below Oxygen Molecules,represented by Unshaded Spheres,and Chlorine Molecules,represented

In figure (1) below oxygen molecules,represented by unshaded spheres,and chlorine molecules,represented by shaded spheres,are in separate compartments.Figure (2) shows the equilibrium state of the system after the stopcock separating the two compartments is opened.Assuming the oxygen and the chlorine behave as ideal gases,what are the signs (+,-,or 0) of ΔH,ΔS,and ΔG for this process?

A) ΔH = +,ΔS = -,ΔG = +
B) ΔH = 0,ΔS = +,ΔG = -
C) ΔH = 0,ΔS = -,ΔG = +
D) ΔH = -,ΔS = +,ΔG = -
