Using the Born Haber Cycle

Well there is no point in running away from these monster cycles. Haber go at this example cycle where I point out some of the potential pit falls so you don't make mistakes. Size matters when it comes to ions, I will go through the size of ions and charge and how this alters the lattice Enthalpy of formation.

THESE VIDEOS ARE LITERALLY SAVING MY WHOLE A-LEVEL

Oustanding explanation. The amout of work and detail went into this video is amazing. Thanks!

[Suzan]

I have watched vaious videos on this topic and so far you are the only person who has cleared up all my questions. Thank you

[Smileysahana]

hi sir, thank you so much for all your videos, youre literally my fav chem teacher i watch you all the time and youre a lifesaver especially during covid!!

please sell some some allery drip. ill rock it to school with pride

It was a very helpful video. Keep it up! Already subscribed btw 😃

Hi Chris thank you for your videos,

Why do you times the delta change of atomisation of fluorine by 2 if you're only breaking one bond from F2---->2F please?

[SsZz]

Hey I'm watching all your vids but I can't find AS unit 2 alcohols and their reactions. E.g secondary alcohols and ketones, if you can direct me to them, it'd be great thanks, !

When working out the born-Haber cycle for Al2O3 and we work out the atomisation energy of Oxygen, do we X the value by 3 (because we form 1 Mole x 3) or do we X the value by 3/2 (because there are 3/2 moles of O2 before we atomise)?
2 different sources have said both the opposite and I'm very confused

[motayee]

If this was a scenario with bond dissociation instead of atomisation, would it be 1/2 F2 forming 1F ? This has been confusing me all year, thankyou or your videos!!!

Hi, I used a different method and got +940kJmol-1. Then using the value to make sure all the numbers = enthalpy of formation and it worked. So I'm not sure which method to use?

thank you for trying to help, but your hand writing is small and i cannot read it very well, also the board is so full and its distracting.. sorry. but thank you very much
