WebApr 16, 2015 · Why do exothermic dissolution reactions occur? I've always been taught that an exothermic dissolution means that the forming of solute-solvent bonds releases more energy than the energy consumed to break solute-solute bonds and solvent-solvent bonds. However, if the attraction that occurs between solute and solvent particles are … WebJun 27, 2013 · Cooking an egg is endothermic because there is a net intake of energy to make the egg cooked. The bottom line is that both endothermic and exothermic reactions involve the breaking of bonds, and both therefore require energy to get started. It makes sense that breaking bonds always takes energy. A chemical bond holds two atoms …
WebIt's really ATP + HOH ==> ADP + Pi. You break a P-O (in ATP) and an O-H (in water), and you also form a P-O (in Pi) and an O-H (in ADP).
