      Hey Niall, I absolutely love Eliot's videos too :-) I'd also recommend this channel, Study Mind, who are launching a free AQA A-level Chemistry course on TH-cam. Good luck with exams all! th-cam.com/channels/zFXGNbYzfgXApJjlVqV_eg.html

    Finished my final chemistry exam yesterday, all I can say is thank you for all your help man, got me through a level chemistry. Its had its ups and downs but its been an absolute blast. Going to miss watching these badass videos but then I remembered I never have to work out how many Cnmr peaks does a benzene molecule have and stopped caring. Who doesn't guess that stuff anyway? But I will forever be grateful for showing me everything there is to know. You taught be to love chemistry, but I'm never doing it again. Fair well you genius and I hope you continue to help the less natural chemists like myself. Thanks again

    Dear Mr Rintoul
    For the past year I have been using these videos to learn various topics as well as revision... They have been extremely helpful and a key factor in my revision. Only believing I would get a C/B on the new AS spec exams I was very surprised to see that I got an A on results day! Thank you so very much for aiding me in achieving this as I couldn't have done it without you. You seriously are a living legend and wish every teacher could be as proactive and as helpful as you!!
    P.S. please can you do the a level new spec material as well as it would be very much appreciated
    Thanks again mate 👌

    For the contact process where you use a catalyst for the reaction between sulphur dioxide and oxygen to produce sulphur trioxide. Isn't that catalyst heterogeneous, not homogeneous?

    • @simitachi4930
      @simitachi4930 7 ปีที่แล้ว

      To balance out the oxygens. Remember, you can only add H2O or H+ to any side when balancing out red-ox in our spec. They made it simple like that for us.

    • @yazzjustheretocomment
      @yazzjustheretocomment 8 ปีที่แล้ว

      Yeah, I think he was, I thought it was Haber before but it's definitely contact since the contact process in the 2nd equation carries on the catalyst intermediate.

  • @ohshami
    @ohshami 5 ปีที่แล้ว

    @Eliot Rintoul I hate to be one of those people but @4:46 you say that Vanadium oxide is a homogenous catalyst.. isn't it a heterogenous catalyst since its in a different phase to the reactants? That is also what it says on the specification.

  • @HE-eg2ue
    @HE-eg2ue 5 ปีที่แล้ว +1

    You know the first few reactions you said they were homogenous, aren't they heterogenous because at the beginning you described how heterogenous catalysis involved different phases so for example gaseous reactants and a solid catalyst and the first few reactions meet this criteria.
