7PRACTICE PROBLEM
Three vessels were occupied by ideal gases X (gray spheres), Y (yellow spheres), and Z (green spheres) separately. The contents of the vessels represent the original state of an isolated system. When the stopcocks are opened, determine the signs (+, −, and 0) of ΔH, ΔS, and ΔG for the process that occurs.
