what is bond dissocation energy?
bond dissociation energy is the energy required (to be given to a compound) to break a covalent bond.
are breaking bonds + or -?
breaking a bond requires an input of energy from the surroundings. (endothermic) thus, the final energy state of the entire system will be higher than the initial. thus, the change in enthalpy or free energy (f-i) of the system will be +.
