Abubla Posted January 27, 2016 Report Share Posted January 27, 2016 Hi my chemistry IA is due tomorrow morning (around 10ish hours) My IA is related to Activation energy and Arrhenius' Equation: lnk = -(Ea/RT) +lnA So in this richard thornley video about the Ea of glow sticks:https://youtu.be/b41fRjI6kuQ?t=1m28she sets the y-axis as the natural log of illumination, can someone explain how or why he is able to do this? and why this works out? because I just can't seem to be able to identify the link as to why ln k is the same as ln of illumination!Thanks Reply Link to post Share on other sites More sharing options...
kw0573 Posted January 27, 2016 Report Share Posted January 27, 2016 I think it has something to do luminenscence is proportional to concentration of the reactants. 1 Reply Link to post Share on other sites More sharing options...
Abubla Posted January 27, 2016 Author Report Share Posted January 27, 2016 I think it has something to do luminenscence is proportional to concentration of the reactants. I looked in to it and I can't really find anything like this explicitly stated anywhere :/ times like these really make me wonder why I took chem HL haha Reply Link to post Share on other sites More sharing options...
GitteVermeer Posted January 27, 2016 Report Share Posted January 27, 2016 I think this is a question for a chemistry teacher... My advice, as a fellow HL Chem student, just do it the way he does, and either don't mention why you made this link or completely bull**** your way around it. If you do it well, your teacher probably won't notice... Good luck! 1 Reply Link to post Share on other sites More sharing options...

Good luck!hahahahha yeah, I tried that but sadly my teacher noticed which is why i'm trying to fix this but if I can't find any answers I'm just going to leave it at:by taking the natural log of both sides of the arrhenius equation we can relate it to y=mx+c (y corresponding to ln k and hence ln lux as its on the y-axis of the graph)thanks tho 1 Reply Link to post Share on other sites More sharing options...
