As the solo chemistry teacher at an international school, introducing the IB, this site literally "saved my skin" -never felt alone and a wonderful resource. Highly recommended

- Hi AustinGeoff is away on holiday at the moment (he may pick up on this when he's back). Given the new syllabus - as you point out, I think it's highly unlikely that SL students would ever get a question about IR activity linking to change...
- Hi Geoff,In question 16, you've given one of the options in relation to the change in dipole moment. In the new syllabus, IR spectroscopy is no longer covered in the Standard Level course and the specification for R1.3.3 links to AHL...
- Hello Helena, Thank you for your kind comment on the latest edition of my Study Guide. I'm glad you and your students are finding it so helpful.On page 102, the equation ΔG = ΔG⦵ + RTlnQ is being used to show how the value of ΔG changes...
- Dear Geoffrey, On pg. 102 of your excellent IB guide, I may be mistaken, but reading under Gibbs energy change and equilibrium constant' , but if Q is 0 lnQ=1, does that not make DG= DG(Standard) + RT, instead of DG= DG(Standard). Kind...
