Chad provides a lesson on how to calculate Cell Potential under nonstandard conditions using the Nernst Equation. The derivation of the Nernst equation is included, and all three common variants of the Nernst Equation are provided. An example calculation is performed, and the qualitative implications of the Nernst equation are explored in relation to Le Chatelier's Principle. Any stress that results in a shift to the right increases the cell potential, and any stress that results in a shift to the left decreases the cell potential.
I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at www.chadsprep.com/chads-gener...

@@ChadsPrep Just a quick question that now after 4 months I came back and it doesn't sit with me- Because the standard cell potential is Cathode minus anode but you wrote it as minus 0.76 volts for zinc and minus 0.28 for cooper(when according to what is written on the internet it actually should be positive 0.34 for cooper meaning cooper is the cathode). Please tell me if my observations are correct or perhaps there is something I am missing here. Thanks a lot in any case!

@@sroydetroy6404 First of all, you are correct in stating that the reduction potential of copper is 0.34V. But the elemental symbol for copper is Cu, not Co. This problem involves cobalt whose elemental symbol is Co, not copper, and the reduction potential for cobalt as written is -0.28V. Hope this helps!

@@ChadsPrep Another question that rose up to my mind since I understand the Nernst equation can be written in many ways - is I understand(from internet sources) that 0.059 and 0.029 are for the passage of 1 mole and 2 moles of electrons respectively. But I didn't quite understand why we are using the value of 0.0275 for the equation with natural log. I get that multiplying it by 2.03 will get you the equation with log base 10 but I didn't get why we are using this number(0.027 and instead of 0.029) in the first place and while we are at it- how do I even know which number to use? sorry if this was a mouth full but this equation has many details in it with whom some of which I still don't understand. thanks in advance.

how to calculate number of electrons if the anode and cathode don't share the same number of electrons????
@taurusequus891
@taurusequus891 Год назад
You need to balance the equation so there's the same number of electrons is on each side
