I prefer walkthrough videos because it demonstrates how to answer the exam style questions while you also explain the theory but I like both styles of videos.
Thank you. This is good to know. I certainly think that I'll keep doing Walkthrough videos during exam season. That seems to be what people value most at this stage
At 10:41 when you combined the 2 equations involving Mn2+ and MnO4-, how come the coefficient of Mn2+ is not 5Mn2+ instead of 4Mn2+? Because aren't you balancing the equations to cancel out the electrons so you multiply the oxidation reaction of Mn2+ by 5?
When the catalyst reacts with MnO4- it only reduces the Mn by 4 electrons. The C2O4^2- reduces the Mn3+ to Mn2+ as the last stage. The Equations written in green after "The Mn2+ reacts..." is for the conversion of one MnO4- to Mn3+. You're right though, if you multiply that equation by 2 and the "Mn3+ reacts..." equation by 5 and combine them, the catalyst cancels out and we are left with the same overall equation as normal

That was so helpful. Thank you so much.
Please can you do one for rate equations.
Will do that next week 😃
Thanks very much, a six marker on autocatalyst came up in the aqa paper 3 exam.
Superb! Nice to know this was useful!

@@chemistrytutor Thank you very much
No worries 👍
