Solved 6. Which of the following statements is not true?

WebThis is due to the fact that the process of breaking bonds consumes energy, whereas the process of creating new bonds results in the release of energy. When bonds are broken in an endothermic reaction, energy is absorbed into the system; on the other hand, energy is released when bonds are formed in an exothermic reaction. WebChemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or use) energy are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in … WebChemical reactions can involve the breaking of existing chemical bonds, the formation of new bonds, or both. The evaporation of sweat does not involve any chemical changes but it does involve a change in physical phase (from liquid to vapour). Therefore, evaporation is said to be a physical endothermic process rather than an endothermic reaction. bozemantrailcampground.com
