What is the relationship between the magnitude of a molecule's bond dissociation energy and its expected chemical reactivity?
remember dissociation energy is the energy required to break a bond between to covalently bonded atoms. dissociation energy corresponds to the strength of a covalent bond. carbon compounds however have very high dissociation energy meaning it would be harder to break the bond between them than it is for a bond of lower dissociation energy. if the bonds cannot be broken then they cannot be used to form covalent bonds and thus are unreactive. they are unreactive partly because their dissociation energy is high. in other words for the slow ones jk lol: the higher the dissociation energy the less reactive. ex carbon compounds like C-C, C-H are unreactive
A higher bond dissociation energy means the covalent bond is?
It means bond is very stable or strong.
What does a high dissociation energy say about the strength of a particular covalent bond?
That this bond is strong and needs a higher influx of energy to have disassociation happen.
What is the bond dissociation energy for typical C-C covalent bond?
Around 154 kJ per mol
How is activation energy related to bond energy?
If the bond dissociation energy for reactants is high then activation energy required for the reaction also will be high.
How is the strength of a covalent bond related to it's bond to its bond dissociation energy?
Greater the bond strength, greater is the bond dissociation energy. (So they are proportional to each other).

How does bond dissociation energy relate to the number of shared electron pairs?
higher is the no of shared pairs of electrons higher will be the bond dissociation energy.
Is Bond dissociation energy positive or negative?
The dissociation of a compound is when a molecular compound, for example: HCl(g) is broken apart to give H+ and Cl- ions when it is dissolved in water. Example the dissociation of compound HCl(g): HCl(g) --(H2O)--> H+ (aq) + Cl-(aq)
The destinguish between bond dissociation energy and atomization energy?
If you product has for example, dissociation of chlorine, it will have 2 atoms of chlorine in atomization, 0.5chlorine on balancing will give you only 1 mole of chlorine atom not 2 moles of atoms like dissociation enthalpy.
How can a covalent bond break?
covalent bonds can be broken if energy is added to a molecule. this formation of covalent bond is accompanied by energy given off.
What type of energy is a measure of covalent bond strength?
Bond dissociation enthalpy (BDE) is a measure of how much energy is required for a bond to break in a molecule or compound. This can be quite low, e. a C-H bond, or extremely high, like a N-N triple bond, which needs almost 1000 kJ mol-1 of energy to break the bond.
