Progress
Hello MCAT Teachers, I wanted a tip from you ensure that I am progressing. I just did the 5E spaced repitition (the thermodynamics passage in the content refresher phase). I got 1/6. I am confident in my knowledge of equilbrium and enthalpy but didn't seem to solve the questions right I got 1/6 with two of the questions…

I don't know how to find an electrochemical's cell reduction potential.
I picked B because I learned for example 1 (on the right) that if we're given 2 reduction half reactions, we could get the oxidized half reaction's reduction potential by subtracting it. Thus, for B, I did "1.78V -(-0.32V)". Why am I wrong? Thank you!

Are all switches resistors? Why does the switch's orientation affect L (resistor length)?
According to the equation on the right, L = the resistor's length. However, I looked at the diagram and saw no schematic symbol for resistors . From the explanation, I get the hunch that the switch is a resistor, but I still don't understand how L increased. Initially the switch was disconnected but present. After the…
