    The way she explains such a complex chapter... it has prepared me for my test and it is quite helpful.

    Ma'am, the way you simplified this complex and convoluting topic in such a simple manner is absolutely phenomenal... Thank you so much.

    I have been watching your videos when I am having my breakfast. (I have finished every video all the way from Kinetics to Organjc synthesis, in 2x speed. Chemical cells is the only topic I have left, and also the core practicals perhaps.)
    They help me loads! And I particularly appreciate how you put past paper questions at the end of a video.
    Thank you again.

    Miss will you ever solve the end of chapter Exam Practice in the book?
    thank you for all your help

    at 30:35 you talked about reversing the top equation, what did you exactly mean by reversing?

      I think, as the question asked for the equation from ethanol to ethanal, the electrode reaction was reversed.

      @@smitaroy9704 yes but what does reversing the electrode mean and does the sign of the electrode potential change as well?

    At 4:10 I'm abit confused bcz u said electrons flow from negative to positive but then u said oxidized to reduced....isn't that positive to negative?

    At 25:49, do we need to know the formula memorised or will it be given in the question paper?

    It it okay to do reduction - oxidation for emf?

    Delta S total is directly proportional to the E cell, and it is also proportional to lnK (where K is the equilibrium constant)
    These values tell us about the feasibility of a reaction.
    The activation energy and k (the rage constant) are linked by the Arhhenius equation, but they have nothing to do with delta S total, E cell, and K (the equilibrium constant)
    Is this a correct way to understand the relationships? Would somebody tell me?
