In figure (1) below argon atoms, represented by unshaded spheres, and neon atoms

Question

In figure (1) below argon atoms, represented by unshaded spheres, and neon atoms, 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 that argon and neon behave as ideal gases, what are the signs (+, -, or 0) of Delta H, Delta S, and Delta G for this process? Delta H = +, Delta S = - Delta G = + Delta H = 0.DeltaS = - Delta G = + Delta H = Delta S = + Delta G = - Delta H = 0. Delta S = +. Delta G = -

Explanation / Answer

H = 0 as no energy change took place

S = +ve = as the system is getting extra space to move

G = -ve = as the process is spontaneous
