Question related to bond dissociation enthalpies and bond order.
The following is a past exam paper question:
(a) Using bond order, compare the following bond dissociation enthalpies and explain the differences: O2 (494 kJ mol-1), O2+ (644 kJ mol-1), N2 (942 kJ mol-1) and N2+ (841 kJ mol-1).
Answer:
• Make O2, O2+, N2 and N2+ molecular orbital diagrams.
• Predict the bond order for these using formula.
[size=medium]• Mention HOMO and LUMO a

Carbon Iodine Bond Dissociation Energy - carbon hybridization
Does anybody know how could vary the C-I bond dissociation energy according to the hybridization (sp3, sp2 or sp1) of the carbon atom?
I know it should be higher for the sp2 than for the sp3 carbon and the lowest should be the sp1 carbon (though for the latter I cannot find any reliable reference).
Any exact value with references?

Acid Dissociation
I'm really struggling with the following problem, and would appreciate some guidance about how to solve it!
"A large volume of 0.150M H2SO3(aq) is treated with a solid, strong base to adjust the PH to 5.50. Assume that the addition of the base does not significantly affect the volume of the solution. Estimate the concentrations of H2SO3, HSO3-, and SO3(2-) present in the final solution. Ka1= 1.5*10-2 and Ka2= 1.2*10-7."

Equillibrium Dissociation constant
Silly question, today we briefly mentioned the equilibirum dissociation constant as the measure of a drugs affinity for its receptor. The professor briefly mentioned if you flip the quotient then you have the assocation constant.
Does he simply mean if you flip the fraction ([L][R]/[L.R]), then that is the dissociation constant?

Question regarding average bond dissociation energy of a C-Cl bond
The dilemma I am having with the following question is that I have the right answer for both part (a) and (b), but I don’t know how to calculate part (a). Even though part (b) can’t be answered without knowing part (a), I was able to calculate it as I was told by a friend what part (a) is. The question is as follows:
[size=medium]Q4. (a) Given that the enthalpy of formation of CH3Cl (g) is -80.83 kJ mol-1 estimate the average bond dissociation energy of a C-Cl bond. (b)
