    At 34.26 minutes of video,
    ∆G = ∆G^o - RT lnQ
    I have 2 textbook here of Gen Chemistry saying that
    ∆G = ∆G^o + RT lnQ
    ^o is to superscript, to set delta G in standard state
    I am learning a lot from you but I like to clarify this formula..Thank you.
    The textbooks are:
    Fundamentals of Chemistry, 4th Ed. by Frank Brescia etc. page 311
    Principles of General Chemistry, 3rd edition by Martin S. Silberberg, page 676

    At 58:26, If you multiply the reaction by 2, wouldn't the half reaction then be 1.54V? And the new total would be 1.77V?
    edit: 1:03:12 The answer is no.

    • @favourfriday7153

      If the reaction is multiplied by a coefficient the cell potential won't be affected or altered.
      It is only altered when the reaction is reversed.

    Mistake at 32:52, this is not a product-favoured system, Q is the initial concentration ratio. However, the positive standard cell potential is indicating that it is a product-favoured system since the reaction is spontaneous.

    whilst most of the content was fairly clear, i was a little mystified at the end where predictions were made as to reaction products at anode and cathode. In my hands on experience, if using HCL as the electrolyte/solvent, you normally see Cl2 being generated at the anode and a codeposition of H2 gas and copper on the cathode. If using H2SO4 as electrolyte, water will be oxidised to O2 at the anode and you still see H2 gas and Cu deposition at the cathode.
