The US didnt join the war until 1917 so u mught want to change that bit. I dont know much more about it though sorry

No it wouldnt, becasue the light acts as a catalysis so the two activation energies wouldnt be equal. I dont know of a way to measure it but as previously stated, the light absorbacne would be small and the reaction involves a fair few intermediates, so its not that straight forward.

I dont know if they ar getting easier or not, but during college, i did Maths Chemistry and Physics at A Level, and Biology at AS, and got all As. The thing is, during my second year, completing the A2 , i also had a part time job of about 25 hrs a week and still got As, even though i didnt do a huge deal of work, Theres something wrong there surely.

Im currently doing an MChem at Bath uni, and am in my second year, I have 8 hrs of lectures with 100+ people, and then 3 Workshops ( 20 people) and 1 tutorial (4 people) a week As well as a day and a half of Labs. A lot of what the previous posts have said applies to me aswell, you are in charge of your learning and if you dont bother working you arent going to do well, Like one of of my lecturers said, for every hour ur in a lecture, u should do 2 extra hours work.

Yea i agree, youll mostly get thermal decomposition to BaO, i remember a demonstation of this in sixth form with 4 bunsens on the go at once. Tough to do in the lab!

The best way to do it is with molecular orbital thory, if u look at O and N+ O has 2 electrons in 2s and 4 in 2p, and N+ has 2 is 2s and 2 in 2p. When the orbitals combine the s orbitals combine to form an antibonding and binding orbitals, so cancel out. The total 6 p electrons combine to form 3 bonding orbitals, with the 3 antibonding orbitals left empty. Gives a bond order of 3, --> triple bond.
