    Just wanted to thank you for creating your channel. You've helped me through my MCAT prep more than words can describe! I'm sure I speak for many other students out there.
    thank you, Chad!

    Hi, why do you put Mn+2 + 2e---> Mn ? the question says Mn/Mn2+. don't they both have to be in oxidization from or anode form? in the video, they are in reduced form or cathode.

    hey got a question:
    why do galvanic cells have a positive cell potential?

    • @ChadsPrep
      @ChadsPrep  3 ปีที่แล้ว +1

      Hello Martin! Galvanic cells have a positive cell potential by definition. There are two major types of electrochemical cells: Galvanic Cells and Electrolytic Cells. The big difference is in spontaneity; galvanic cells are spontaneous and therefore have a positive cell potential and negative delta G, whereas electrolytic cells are nonspontaneous and therefore have a negative cell potential and a positive delta G.
      Hope this helps!
