All diagrams in this video were made by using the Chemix.org software. Major thanks to them for allowing me to use their software in my tutorials.

Wow, thank you!
Thank you so much for the explanation. By far the best video I’ve seen explaining SHE !!!

Appreciate all these vids!!!
Hi, I'm going to get very bad grade in the exam and after than I have to sit as a private candidate. The nearest centre does the AQA instead of OCR. I dont understand what should I do in that case, because of the differences of content. Can you please help me with that. Thanks.

Hi - contact the centre in this scenario and they may let you sit the alternative exam board but with their regular students. Try not to worry though and just do your best
Hi sir could you do a video presentation for the Arrhenius equation in the rates topic !xxx

Hi Mr Murray, I have a quick question, whee can we find an accurate list of all the definitions we need to know please?

Mini hack for you = go to the OCR or AQA spec and search the document for either ‘definition’ or ‘define’ and then go though each of the mentions in the list

Why does the voltmeter read a negative voltage. Is it a problem.

It reads as negative because of how the position of equilibrium compares to that of the SHE. Remember this is all done to try and record a standard electrode potential and some of these are negative values. Check this out too = kzread.info/dash/bejne/d3qtrKucg9aWfsY.htmlsi=au3JBSzjhBFwq_on
The left hand side means it should be the anode. Correct me if i am wrong.

The SHE always goes on the left. As it’s the basis of the electrochemical series, we place it here for consistency as we don’t know the electrode potential of the other half cell yet so we don’t know which is more negative (yet)
your voice is beutiful holy shit
