i can honestly say i love you

Very important for any of you doing AQA chemistry A2, 1/2Br2 going to Br is actually called the Bond dissociation enthalpy, and remember, it is given PER MOLE. Which James doesn't take into account in this video or doesn't tell us he does. Therefore you have to half the value. And also, direction of arrow on this course is very important. Endothermic processes point up and exothermic point down, therefore the electron affinity should be the other way round! Good luck guys!

haha same thing happened to me, staring at lecture notes for an hour 'what the hell is this' Watch this 2min vid, Click!

Thank you sooo much :)

*CLICK* did anyone else hear that huge click in my brain!?!? THANK YOU SOO MUCHHH I GET ITT AHHHHH YAY CHEMISTRYY i read about the cycle like 8 times in my book, but watched this once and BAM! godspeed
