Break bonds negative
WebScience; Biology; Biology questions and answers; Why does the hydrolysis of ATP into ADP and Pi have a negative G (is thermodynamically favorable)? If energy has to be used to break bonds (like the one holding the phosphate group on the rest of the molecule), why does ATP hydrolysis release energy that can be used to power other endergonic reactions? WebGenerally, a positive change in enthalpy is required to break a bond, while a negative change in enthalpy is accompanied by the formation of a bond. In other words, breaking a bond is an endothermic process, while the formation of bonds is exothermic. Bond Enthalpy or Dissociation Energy

WebThe energy change is negative, due to the fact that the energy released by the bonds formed is greater than the energy absorbed by the bonds broken. This means that … Weba chemical change-chemical reaction-converts one substance into another; heart of chemistry; involve breaking bonds in the starting materials, called reactants, and forming new bonds in the products. -ex. combustion of methane (CH4) in the presence of oxygen, forms CO2 and H2O.
WebSo the summation of the bond enthalpies of the bonds that are broken is going to be a positive value. And since it takes energy to break bonds, energy is given off when bonds form. So next, we're gonna sum the bond enthalpies of the bonds that are formed. And notice we have this negative sign in here because this energy is given off.
