1. When two atoms form a bond their potential energy (1) decreases; (2)increases; (3) remains the same; (4) varies. How do you related this to spontaneous process?
2. In a chemical reaction, the products have a lower potentialenergy than thereactants. This reaction must have a negative (1) DG; (2) DS; (3) DH; (4)DX. Can you explain why?
