WebValues Endothermic - Energy must be put in to break any chemical bond Examples Cl2(g) ———> 2Cl(g) O-H(g) ———> O(g) + H(g) Notes • strength of bonds also depends on environment; MEAN values quoted • making bonds is exothermic as it is the opposite of breaking a bond • for diatomic gases, bond enthalpy = 2 x enthalpy of ... WebThat's their heats of formation. So Hess's Law tells us that delta H of this reaction, the change in enthalpy of this reaction, is essentially going to be the sum of what it takes to decompose these guys, which is the minus heat of formations of these guys, plus what it takes to reform these guys over here. So we can just write it as delta H of ... bonis imposable
